Question
Please explain!
The electric field everywhere on the surface of a thin, spherical shell of radius 0.745 m is of magnitude 935 N/C and points radially toward the center of the sphere. What is the net charge within the sphere's surface? What is the distribution of the charge inside the spherical shell? 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. The positive charge has an asymmetric charge distribution.
Explanation / Answer
a) on surface E = kq/r^2
charge is negative since it points inwards
q = -935*.745^2/9E9=-57.66 nC
b) negative charge is symmetric so first choice
