Question

The electrostatic potential of a uniformly charged thin spherical shell of charge Q and radius R at a distance r from the centre

Answer 1

Electrostatic potential:

The amount of work required to move a unit charge inside the field is called as electrostatic potential.

When the point 'r' is inside the spherical shell:

r ≤ R

The electrostatic potential is given as:

U = kθ/R

∴ U = 1/4πε₀ × θ/R

When the point 'r' is outside the spherical shell:

r > R

The electrostatic potential is given as:

U = kθ/r

∴ U = 1/4πε₀ × θ/r
