An uncharged metal sphere suspended by a silk thread is placed in a uniform external electric field E.(a)What is the magnitude of the electric field of points inside the sphere?(b)Is your answer changed if the sphere carries a charge?
I would have asked this in homework forum but it does not involve any calculations and I have also been provided with it's answer ,I am just going to ask a conceptual question based on the answer
Answer:(a)##E##=0
(b)No
As we can see there is silk thread then there is external field to confuse the student that there is a special kind o set up hence there can be ##E##≠0 inside the metallic/conducting sphere but the answer is as usual ##E##=0 So it Does it mean ##E##=0 inside the metallic/conducting sphere no matter what.
Or are there any examples any set up any situation where ##E##≠0 inside the metallic/conducting sphere
