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 880 N/C and points radially toward the center of the sphere. What is the net charge within the sphere's surface? __________ nC What is the distribution of the charge inside the spherical shell? The positive charge has a spherically symmetric charge distribution. The negative charge has a spherically symmetric charge distribution. The positive change has an asymmetric charge distribution. The negative charge has an asymmetric charge distribution.

Explanation / Answer

a)The electric field of a spherical shell is given by

E = Q/4 pi epsilon0 r^2

We need to find Q

Q = E (4 pi epsilon0) r^2

Q = 880 x 4 x 3.14 x 8.85 x 10^-12 x 0.74^2 = 53.56 x 10^-9 C

Hence, Q = 53.56 x 10^-9 C = 53.56 nC

b)The charge has spherically symmetric charge distribution.
