Electrostatic Potential and Capacitance

Question:

A charge q is placed inside a spherical cavity, made in an uncharged conducting sphere of radius R as shown. A point charge Q is placed at a separation d from the centre of solid sphere as shown in the figure.

Column A

Column B

A. Electrostatic potential at point X inside the conductor

 p. $\frac{kQ}{d}+\frac{kq}{R}-\frac{kq}{r’}-\frac{kQ}{r}$

B. Electrostatic potential at point O

 q. $\frac{kQ}{r^2}$

C. The magnitude of the electrostatic field at point X inside the conductor due to the charges induced at the outermost surface only 

 r. $\frac{kQ}{r}$

D. Electrostatic potential due to all the induced charges at point X inside the conductor

 s. $\frac{kQ}{d}+\frac{kq}{R}$
