JJ Thompson's measurement of the charge to mass ratio of electron 

As an 11th grader from India, I find this very helpful! Thank you so much for the very clear explanation!! :D

Very clear explanation! Thank you!

Thank you, couldn't find any better explation.

I don't understand very well the why the expression of q/m = 2yxE/(L^2×B^2) holds if the displacement y is zero for Fb=-Fe. It is a bit puzzle to me.

I'm confused at how scientists determined that north and south pole attract opposite charges, please help

the electron source was metal plates or ionisation of gas taken in the tube?

How would one go about plotting a graph with just the measured quantities. Is it possible to graph in a way that the slope could give charge to mass ratio?

Very good explanation!

Thanks

thank you madame curie

there is actually a problem with the formula about the deflecting electric field. since the field does not exist everywhere, the bias of y should not be determined by the time that the electron passes through the field. just my little notion.

Well what’s weird symptoms in this test could show if changing the way to pushing or set up traffic lights. Find common

So, electric potential can also give off kinetic energy!

Good

What is y

beg you to reply

Arstralian dont say "Here" they be sa "Heeeeee -Arrrrrrr"
