I researched this painting was made by Karl Schmidt- Rottluff. His Aquarell - Paintings are very beautiful an perfect. I know, that beauty is not a creterion of good Art, but nevertheless his Aquarells are very beautiful.
Sir u have a doubt If we take 2 different point charges at a distance of 3m and 1.5 meter is filled with water and rest with air how to calculate electrostatic force between them please explain
I can't find it's name! But surely, there is a serendipity in the air I couldn't smell it on time . Yet the treachery of the language made of different tongues allow me to wonder of my Hyena's.😅
Sir can both Net positive and negative charge be induced in case of a conductor, by only using one kind of charge for the induction process? Say if the inducing charge was positive, then if we attach the earthing wire to the negatively polarized side, the excess electrons will flow to the earth, giving us Net Positive charge once (1st, the wire) the inducing charge is removed.. And if we attach the earthing wire to the positively polaized side, then the free electrons from earth will flow towards it, giving us Net negative charge once (1st, the wire) the inducing charge is removed. is this possible? Edit: Sir please allow me to clarify. We know that we can charge a body by the method of charging by conduction. So, my teacher taught me that, if we are charging a neutral body by induction, and, if that body is a metal or an ideal conductor, then the charge which we will finally induce onto it will always be of the same magnitude, but of opposite nature, as the charge we used to induce or charge that ideal conductor. Let's say the Inducing charge is '+Q'. Thus the induced charge will be '-Q'. Now, we were also taught the method to achieve such charge by using the method of grounding. If we bring a positively charged rod close to a neutral conductor, then the side closer to the conductor will be negatively polarized, and, the side away from it will be positively polarized. Now if we attach a grounding wire, to the side which is away from the positive rod,i.e., which is positively charged, then electrons will flow, from the earth, to the ideal conductor's positive side, to eventually neutralize it, leaving the other side, and the whole conductor, net Negatively charged. Once we remove the grounding wire, and then the positively charged rod, the induced negative charge, will spread out uniformly on the surface of the conductor. Now essentially, what my query was, is that what would happen, if we, instead of attaching the grounding wire to the positively polarized side of the conductor, what if we attach the grounding wire to the negatively polarized side of the conductor, i.e, closer to positive rod. Will electrons from the earth and grounding wire get attracted and accumulate on the side closer to positive rod. [While writing this, I am realising not much would happen. The electrons from the earth and grounding wire cannot move and accumulate to the ideal conductor's side closer to the positive rod, due to repulsion from already accumulated electrons from the (initially neutral) ideal conductor. Also, the electrons from the conductor, can't move into the earth due to the attraction force that they are under via the positive rod]

Can we use the same (natured) charge to charge a neutral body by induction, both negatively and positively? [By writing this, I am realising that maybe this can't happen because of the repulsion forces by the already accumulated electrons of the (initially neutral) conductor. Also, the electrons from the negatively polarized side may also not get conducted into the earth because of the attraction force they are feeling due to the positive rod]
@@PainofTheaction I have no idea what you are talking about. In short, you can put + charge and/or neggative charge on any body (metal or not). *However, you can not create + or - charge*
@@lecturesbywalterlewin.they9259 Extremely sorry sir for wasting your time. I will try to improve my communication skills in English in future because it is not my mother tongue. Also, I just started this chapter of Electric charge and fields so I much likely am speaking gibberish. Thank you so much for your time. Regards.
@@PainofTheaction key is that you can move charges around in many ways - you can also separate charges in a conductor using polarization. You can charge any one object with ONLY neg or with ONLY pos charges. BUT if you have charged an object with 1.03007 mC *negative* charge, then 1.03007 mC *pos* charge must also be somewhere (maybe on the Moon) but it must be somewhere.
