An insulating sphere with a radius of 0.100 m has a charge of 0.965 nC uniformly distributed throughout its volume. The center of the sphere is a distance 0.295 m above a large uniform sheet that has a charge density of -7.90 nC.
Find the distance from the center of the sphere to the point inside the sphere at which the electric field is zero.
r < R
E = 1/4pi*E_o * Qr/R^3
Is there only 1 sphere that is directly above the sheet that is 0.295m ? I'm not exactly sure how the picture looks, so I wanted to verify this and then what to do next.
