Find the work done by some external force in moving a charge q=4 muC from infinity to a point, where electric potential is 10^(4)V

Show that the work done by an external force in bringing a unit positive charge from infinity to a point is equal to electrostatic potential (V) at that point.

A charge q=2muC is moved by same external force from infinity to a point where electric potential is 10^(4) V .Calculate the work done by external force.
