    What is the work done by the electric force on uint charge ?

    Lift an object up from the ground. Work done by the force exerted by you on the object moves it in upward direction. Thus the force applied iis in the direction of displacement. However there exists a force gravitational in the object at the same time * Which one of these forces is doing positive work ? * Which one is doing negative work ? * Give reasons.

    Can you find the work done by the electric force ?

    What do you call the work done by the electric force on unit positive charge to move it ?
