An insulating spherical shell with inner radius 25.0 cm and outer radius 60.0 cm carries a charge of + 150.0 ?C uniformly distributed over its outer surface. Point a is at the center of the shell, point bis on the inner surface and point c is on the outer surface.

Part A

What will a voltmeter read if it is connected between a and b?

?Vab =   V

Part B

What will a voltmeter read if it is connected between b and c?

?Vbc =   V

Part C

What will a voltmeter read if it is connected between c and infinity?

?Vc? =   V

Part D

What will a voltmeter read if it is connected between a and c?

?Vac =   V

Part E

Which point is at higher potential, a or b?

Which point is at higher potential,  or ?
 a is at higher potential than b b is at higher potential than a a and b have equal potentials

Part F

Which point is at higher potential, b or c?

Which point is at higher potential,  or ?
 b is at higher potential than c c is at higher potential than b b and c have equal potentials
