 A solid metal sphere of radius 2.00 cm lies at the centre of a hollow metal sphere of inner radius 4.00 cm and outer radius 6.00 cm. The system is in electrostatic equilibrium. Point A lies 3.00 cm from the centre. The electric field at point A points radially outward and has a magnitude of 1.00x104 N/C. Point B lies 8.00 cm from the centre. The electric field at point B points radially inward and has a magnitude of 1.00 x 104 N/C.
