Question

A point charge of -3.00 μC is located in the center of a spherical cavity of radius 6.60 cm inside an insulating spherical charged solid. The charge density in the solid is 7.35 × 10 −4 C/ m^3 .

Part A Calculate the magnitude of the electric field inside the solid at a distance of 9.40 cm from the center of the cavity. Express your answer with the appropriate units.

Part B Find the direction of this electric field.
