The electric field everywhere on the surface of a thin, spherical shell of radius 0.710 m is measured to be 860 N/C and points radially toward the center of the sphere.
(a) What is the net charge within the sphere's surface?nC
(b) What can you conclude about the nature and distribution of the charge inside the spherical shell?
the positive charge has a spherically symmetric charge distribution or
the negative charge has a spherically symmetric charge distribution or
the negative charge has an asymmetric charge distribution or
the positive charge has an asymmetric charge distribution
