The electric potential at the centre of two concentric half rings of radii $R_{1}$ and $R_{2}$ , having same linear charge density $λ$ is

Question diagram: The electric potential at the centre of two concentric half

Options:

Answer:

Solution:

$V_{O} = V_{1} + V_{2}$

$\Rightarrow V_{O} = \frac{1}{4 π ϵ_{0}} \times \frac{λ_{1} (π R_{1})}{R_{1}} + \frac{1}{4 π ϵ_{0}} \times \frac{λ_{1} (π R_{2})}{R_{2}} = \frac{λ}{2 ϵ_{0}}$
