PhysicsEasysingle choice

Two concentric spherical conducting shells of radii $R$ and $2 R$ carry charges $Q$ and $2 Q$ respectively. Change in electric potential on the outer shell when both are connected by a conducting wire is

Options:

Answer:

Solution:

The initial potential at the outer shell

$V_{1} = \frac{k Q}{2 R} + \frac{k 2 Q}{2 R} = \frac{3 k Q}{2 R}$

The final potential at outer shell is

$V_{2} = \frac{k 3 Q}{2 R} ∴ Δ V = V_{1} - V_{2} = 0$
