Two infinite parallel plastic sheets contain equal negative charge densities uniformly spread over their surfaces.The electric field is zero everywhere between these sheets,not just midway between them.

Question

Quizplus · Accepted Answer

Since the electric field is zero everywhere between the sheets, it means that the attraction force between the negative charges on the sheets is balanced, resulting in no net electric field. This can only be achieved if the charge densities on the sheets are equal and uniformly spread over their surfaces.
