[SOLVED] Voltage Query
An insulating spherical shell with inner radius 25.0 cm and outer radius 60.0 cm carries a charge of + 150.0 [tex]\mu C[/tex] uniformly distributed over its outer surface. Point a is at the center of the shell, point b is on the inner surface and point c is on the outer surface
What will a voltmeter read if it is connected between c and infinity?
[tex] V = \frac{1}{4\pi \epsilon _0}\frac{q}{r} [/tex]
In my textbook,it says that any voltage between a point and infinity will equal 0, but entering 0 says it is wrong.
Using the above equation, how do you put the radius shou.d equal infinty
Any Ideas?
