Question

Drive an expression for electic potential due to
a point charge .​

Answer 1

Answer:

Electric potential of a point charge is V=kQr V = k Q r . Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field.
