A thin spherical shell is charged by some source. The potential difference between the two points C and P (in V) shown in the figure is: (Take 1/(4πε₀)=9×10⁹ SI units)

Question

Accepted Answer

(2) Zero. The field inside a uniformly charged thin shell is zero, so the potential is the same at every point inside it and on it: V=(kq)/R. C is the centre and P is on the shell, so both are at (kq)/R=(9×10⁹×10⁻⁶)/(0.03)=3×10⁵ V. V_C-V_P=0.
