Question

A small ball with a net uniform positive charge of 50 nC and a radius of r = 0.2 cm is surrounded by a concentric thin spherical shell with a uniform negative charge of -50 nC and a radius of R = 1 cm. Find the net electric field (E) produced by the shell at the ball surface.

Accepted Answer

E = 0 N/C

Answer

E = -7.0 × 10² N/C

Answer

E = 4.5× 10² N/C

Answer

E = 7.0 × 10² N/C
