Solution for problem 25RQ Chapter 22
Why is there no electric field at the center of a charged
Conceptual Physics | 12th Edition
Why is there no electric field at the center of a charged spherical conductor?
Solution 25RQ Because the mutual repulsion, mobile electrons in the conductor will spread out uniformly over the outer surface of the ball, so the force and the field on a test charge at the center is zero because opposing forces balance in every direction.
