Consider a solid conducting sphere with an
inner radius R1 surrounded by a concentric
thick conducting spherical shell which has an
inner radius R2 and outer radius R3. There is
a charge Q on the sphere and no net charge
on the shell.
For all parts of this problem, we adopt
the standard convention of setting the electric
potential at infinity to zero.
Find the potential at Point A.
Find the Potential at Point O.
I have posted the problem and the choices. it is questions 10 and 11.
The Attempt at a Solution
I think that the potential at point A is: 3. Va= KQ/a
For Point O: either 0 or infinity
Can somebody please tell me if I am correct. Thanks in advance.
