A hollow metal sphere has inner and outer radii

Reference no: EM13677294

A hollow metal sphere has inner and outer radii of 6cm and 10cm. A point charge is located at the center of the sphere. The surface charge density on the inside surface is -100 nC/m^2. The surface density on the outer surface is +100nC/m^2. What are the direction and strength of the electric field at the points 4, 8 and 12cm?
