The electric field everywhere on the surface of a thin, spherical shell of radiu

Question

The electric field everywhere on the surface of a thin, spherical shell of radius 0.740 m is of magnitude 859 N/C and points radially towards the center of the sphere. (a) What is the net charge within the sphere?s surface? __________ nc (b) What is the distribution of the charge inside the spherical shell? The positive charge has an asymmetric charge distribution. The negative charge has a spherically symmetric charge distribution. The positive charge has a spherically symmetric charge distribution. The negative charge has an asymmetric charge distribution.

Explanation / Answer

applye elctric field E = Kq/r^2

so

charge q = Er^2/K

q = 859 * 0.74 *0.74/(9e9)

q = 52.26 nC

--------------------

as it is readially directed outwards, this must be +ve symmetric charge distribution

option C it is
