Unformatted text preview: 61. If the electric potential is zero at infinity then at the surface of a uniformly charged sphere it is V = q/4πε0 R, where q is the charge on the sphere and R is the sphere radius. Thus q = 4πε0 RV and the number of electrons is N= |q | 4πε0 R|V | (1.0 × 10−6 m)(400V) = = = 2.8 × 105 . 2 e e (8.99 × 109 N · m2 /C )(1.60 × 10−19 C) ...
