The electric field everywhere on the surface of a charged sphere of radius 0.260 m has a magnitude of 545 N/C and points radially outward from the center of the sphere.

Question

The electric field everywhere on the surface of a charged sphere of radius 0.260 m has a magnitude of 545 N/C and points radially outward from the center of the sphere.
(a) What is the net charge on the sphere?

drwls · Answer

Use Gauss' Law. The total flux is 4*pi*R^3 *E Gauss' Law tells you how to relate the flux to the total charge. Flux = Q/epsilon0 epsilon0 = 8.854*10^-12 C^2/(n*m^2)
