Question

A thin spherical shell of radius R1 = 3.00 cm is
concentric with another larger thin spherical shell of radius
R2 = 5.00 cm. Both shells are made of insulating material.
The smallest shell has a charge q1 = +6.00 nC distributed
evenly on its surface, and the largest one has a
charge q2 = -9.00 nC evenly distributed on its surface
ficie. Consider the electric potential equal to zero at an in-
finite of both shells. a) What is the electrical potential due
to the two shells at the following distances from their common center
i. r = 0; ii. r = 4.00 cm; iii. r = 6.00 cm? b) What is the magnitude of
the potential difference between the surfaces of the two shells?
Which shell has a greater potential: inside or outside?
