The electrostatic potential at a point on the surface of a charged spherical conducting shell of radius 10 cm is 120 V. The electric potential at a distance of 5 cm from the centre of the shell is:

120 V

The correct answer is Option (4) → 120 V

Since, the point of interest (5cm from the center) is inside the conducting shell, the potential at that point will be same as the potential at the surface of the shell.

$V(5cm)=120V$
