Question

Equipotential surfaces are denser (closer together) in regions where:

Options

• The electric field is weaker

• The electric potential is zero

• The electric field is stronger

• The charge is negative

Answer 1

Using the relation \[E = -\frac{dV}{dr}\], where the potential changes rapidly (strong field), the equipotential surfaces are closer together. Greater E means potential changes faster, so surfaces are denser; weaker E means potential changes slowly, so surfaces are farther apart.
