Electrostatic Potential and Capacitance

Question:

A cavity is taken out from a uniform conducting sphere. Inside the cavity a dipole is placed as shown in the figure. Potential at point P is

Options:

$\frac{q l \cos \theta}{4 \pi \varepsilon_0 d}$

Zero

Insufficient information

none of these

Correct Answer:

Zero

Explanation:

Charge on the outside surface of conducting sphere is zero so field or potential at any point outside the sphere is zero.
