Conductors and Dielectrics in an Electric Field

Problem 3.55

A point charge \(q\) is located at a distance \(l\) from the infinite conducting plane. What amount of work has to be performed in order to slowly remove this charge very far from the plane.

Reveal Answer
A=q216πε0lA=\frac{q^{2}}{16 \pi \varepsilon_{0} l}
