Ejercicio Problem - Electric potential, work and electrosta… · Física II URV Juny 2022

System setup

A point charge of $-1\text{ nC}$ is located at the center of a conductive spherical shell in electrostatic equilibrium, having inner radius $r_1 = 2\text{ cm}$ and outer radius $r_2 = 4\text{ cm}$. The shell has a net charge of $+3\text{ nC}$.

Assume the permittivity of vacuum to be $\varepsilon_0 = 9 \times 10^{-12}\text{ C}^2/(\text{N}\cdot\text{m}^2)$.

c.

The electric potential on both the internal and external surfaces of the shell.

d.

The electric field and electric potential at a distance of $5\text{ cm}$ from the central charge.
