A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre:
decreases as r increases for r < R and for r > R
increases as r increases for r < R and for r > R
is zero as r increases for r < R, decreases as r increases for r > R
is zero as r increases for r < R, increases as r increases for r > R
According to Gauss's Law, for a uniformly charged spherical shell of radius : 1) Inside the sphere (), the electric field is zero because the Gaussian surface encloses no charge. 2) Outside the sphere (), the shell behaves as if the entire charge is concentrated at the center, and the electric field behaves like that of a point charge, given by . Thus, for , the electric field decreases as increases ().
