Question

An infinitely long thin wire, having a uniform charge density per unit length of $5 nC/m,$ is passing through a spherical shell of radius $1 m$, as shown in the figure. A $10 nC$ charge is distributed uniformly over the spherical shell. If the configuration of the charges remains static, the magnitude of the potential difference between points P and R, in Volt, is ______. [Given: In SI units $\frac{1}{ 4πϵ0} = 9 × 10^9 , ln \ 2 = 0.7$. Ignore the area pierced by the wire.]

Answer 1

The correct answer is :171
