Question

Do the equipotential lines get closer together or further apart at a sharp corner of a conductor? What about electric field lines? What does this indicate about the electric field strength in this region?

Answer 1

If the electric field linens are closer to each other it indicates that the strength of the electric field.

Closer to the conductor the electric field line density ( field lines per unit area) is more which indicates that the electric field strength is high.

At the sharp corners the electric field line density decrease which indicates weak electric field.

Close the electric field lines ---high electric field strength.

Open electric field lines-- low electric field strength
