Define the electric potential at a point as the work done per unit positive charge to bring a small test charge from infinity to that point.
No lesson yet
Recall and use the fact that the electric field at a point equals the negative of the potential gradient there.

For the field of a point charge, use V = Q / (4πε₀r) for the electric potential.
