A point charge of -2.03oC is located in the center of a spherical cavity of radius 6.52 cm inside an insulating spherical charged solid. The charge density in the solid is 7.35×10-4C/m3
A) Calculate the magnitude of the electric field inside the solid at a distance of 9.50 cm from the center of the cavity.
B) Find the direction of the electric field inside the solid at a distance of 9.50 cm from the center of the cavity.
