I am having few doubts while studying electric field which i am putting here
Suppose there is a spherical metallic shell with point charge q1 at the center and q2 charge outside the sphere in space ...
1) Now what I have have read in this forum and on other places is that the induced charges rearrange themselves in such a way that they cancel the external electric field such that the electric field within the conducting shell is zero .
Now ,when we say external electric field ...do we mean electric field due to q2 as well as q1 ?
2) The force experienced by charge q1 placed at the center of the shell will be zero .
I am not sure about the reason behind this .The force can be zero only when the electric field at the center of the shell is zero .
Why is electric field zero at the center of the shell .What about the effect of outside charge q2 on q1 ?
I would be highly grateful if somebody could help me in clearing the concepts .
Thanks
