Bringing a unit positive charge from infinity to a point, without acceleration, measures the point's:
AElectrostatic potential
BElectric field strength
CSurface charge density
DCapacitance value
Answer & Solution
Correct answer: A. Electrostatic potential
1. Infinity is the chosen zero of potential.
2. The work done per unit charge from there is the definition.
3. It is the electrostatic potential at the point.
