A point charge of -3.00 μC is located in the center of a spherical cavity of radius 6.50 cm inside an insulating spherical charged solid. The charge density in the solid is 7.35 x 10-4 C/m³. Calculate the magnitude of the electric field inside the solid at a distance of 9.40 cm from the center of the cavity. Find the direction of this electric field.
