Electrostatic Potential and Capacitance

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 14πε0=9×109\dfrac{1}{4\pi\varepsilon_0} = 9 \times 10^{9} SI units.)

Question 34 as printed in the NEET 2024 booklet

  1. A.1×1051 \times 10^{5}
  2. B.0.5×1050.5 \times 10^{5}
  3. C.Zero✓
  4. D.3×1053 \times 10^{5}

Solution

Inside a charged spherical shell the field is zero, so the potential is the same at every interior point (and equal to the surface value). The potential difference between C and P is zero.
