😂😂😂sahi kaha jab teacher ko hi jo pdhate hai uska concept ni pta hoga toh hume kya padenge aur fir number kam aane se bolte hai pdte ni aur teacher khud expect krte hai ki baccha coaching jta hoga
Very simple it is if you want i can explain in other view just think energy conservation and tendency of body to stay or attain minimum state of energy you'll find your answer in just 1 sec if you love physics
@@Shubham-wu5jv it's all Upto our minds ability to reach conclusion with high accuracy in less time. It can be inbuilt like tesla or Einstein or it comes with efforts so here is no ones fault all have mind but no one focus on solving instead seeing body and how dir is teaching 😉😂
@Manoj Kumar i guess the concept of rigid body....if the centre of mass(in this case geometric centre) if it goes down....then the respective body parts...the handle...the instantaneous top/bottom points all go down...centre of a body agar niiche aayega to meaning yeh hua na ki whole body hi niiche aa rha h...u r commenting on one point of the body...but since the body is a "rigid body" u r indirectly commenting on all the other respective points of the body...
As a matter of fact, in both the cases either cone or rod, both are moving towards lesser potential. As easy as it can get. Aur Verma sir ki explanation to apne aap me khubsoorati ki misaal hai ek.
Yes, for there to be a motion there must be some potential to come across (with no force applied). The only reason it defies expectation is the geometry of the cones
The triangular shape of that hollow wedge and the shape of the double cone syncs perfectly to allow the double cone to dip inside of the gap giving it scope to move forward and slightly downward due to gravity thus giving and illusion that its moving uphill against the mighty force of gravity.

At 7:38 the boy says that somehow the component of friction manages toovercome gravity and get the cone move up the incline and HC Verma sir also approved his answer but my argument is that, the moment the double cone starts moving up, the friction starts to act in downward direction, so now the gravity as well as friction acts in downward direction and now the cone doee not have any force acting in upward direction. Thus, the student's explaination makes no sense to me. The best possible explaination is only that in the upper situation the COM can go inside and be stable (by having low PE) so that is the stable equilibrium position for the double cone. Please correct me if I am wrong.
One end,,, upward force is equal to downward force. It is in equilibrium... In the other end upward force is higher than downward force,,,so the upward force tend to move towards the downward force in order to aquire equilibrium ... And that makes the double cone move forward direction.
Sir I'm not lying maine yhi and chose kiya tha wo v same explanation k sath basically I'm in 12th now ...but what to say don't knw only huge fan of ur knowledge 🙏🙏🙏
At the end of the video everything got mixed cone, danda, motion, physics, space, time, planet, universe, singularity, infinity and so on😆🤣😆 i forgot even what the question was..... Thumbs up to the physics.....👍👍
That was a nice explanation, adding to that, one must understand MOI ( moment of Inertia ) consider the two axes, one through CG and another instantaneous through plane of track. I=mr² , r is distance from its cg to it's outermost axis we considered. Now we have numerical value , it will go up until the distance between two axes becomes zero that is r =0 which makes I = 0 at the end. Hope my answer helps people who are looking for more mechanical analysis of the situation. Always looking for further discussion over it or any correction will be appreciable.🙏 Adding more fun to that, I wanna add gravity will play it's role and it's still playing it's role, but it destroys all of it. At what condition is it going to happen?😀
मैं समझ गया।।। दुनिया में जो भी event होता है तो वो अपनी system की potential energy कम करता है,, और इस परिस्थिति में कोन का center of mass नीचे आ रहा था जब कोन slope के उलट ऊपर जा रहा था।।। , अगर समझ में आया तो hit like...
Bilkul.lower the energy higher the stability...so is in the case of electron in atom and this double cone a million times huge than electon..so this is a fundamental law of nature..
2/3 is right answer..... I think..... Because center of mass goes down... Ye tohh h... Other things is that body will start to move when instantaneous top most point goes down....
Figured it out in a jiffy as soon as the question was asked. The solid will go down until its handles are in contact with the inclined plane after which the shape of the solid will not be conducive to propel the solid (its centre of mass) any further down because its cylindrical handles form an obstruction unlike the curvature of the cones that aid its motion. Hence, this solid will go down until there is obstruction from the handlebars. Also, the motion of this object is not parallel to the ground (calls for imagination) due to the conclusion made above and so, it is all going down. I know I'm late, blame the algorithm! :-)
05:43 only she got it right and had courage to tell... 6:20 just followed her after little analysis... 7:43 sadly this kind students get growing day by day 4:36 Center of gravity lies always on the lowest point 😂..dekho dekho 😂😂
The double cone goes from an apparently lower level to apparently higher level because in reality, the Centre of Gravity of the double cone is decreasing in that direction and the movement is actually from a higher position (higher CG) to lower position (lower CG).
12th के बाद जो चैनल सबसे ज्यादा आपकी हेल्प करेगा वो है #TechnicalPhysics मुझे लगता है हर फिजिक्स स्टूडेंट्स को एक बार उनके वीडियो देखना चाहिए फिर आप खुद ही जान जाओगे No Doubt for HC Verma sir
I can't believe that people in this video couldn't thought that the double coned object was Solid, and if a single point of that object went down than the other have to go down..., They were getting confused between 2nd & 3rd options... I answered in my mind that all the options are correct..
