Electrostatic Potential due to a Point Charge
Electrostatic Potential due to a Point Charge
The electrostatic potential in bringing a unit positive test charge from infinity to a point P against repulsive force of another positive charge is always positive . o If the charge Q is negative , the potential is also negative as the test charge will have a force of attraction . o Electrostatic potential is inversely proportional to r and electrostatic field is inversely proportional to square of r .
