Passage / Comprehension

There is a cubical cavity inside a conducting sphere of radius R. A positive point charge Q is placed at the centre of the cube and another positive charge q is placed at a distance l (>R) from the centre of the sphere. The sphere is earthed

Net charge on the outer surface of conducting sphere is

Options:

Answer:

Solution:

The potential of the sphere is zero as it is earthed, so the potential at the center, $V = 0$ .
