A thin spherical shell with radius R1 = 2.00 cm is
concentric with a larger thin spherical shell with
radius R2 = 6.00 cm. Both shells are made of
insulating material. The smaller shell has charge
q1 = + 6.00 nC distributed uniformly over its
surface, and the larger shell has charge
q2 = – 9.00 nC distributed uniformly over its
surface. Take the electric potential to be zero at an
infinite distance from both shells.
