Recall / Warm-Up

The work done by a constant force $F$ over a displacement $d$ is $W = Fd$ . Which energy principle directly connects this to electric potential energy?

Conservation of energy: work done by the field equals the decrease in electric PE.

Work equals force times time.

The electric field does work only when charge is stationary.

Potential energy is only defined for gravitational forces.
