If positive charge is displaced against the electric field in which it was situated ,then work will be done by electric field on the charge it will be option A.
Explanation:
- Electric field intensity at any point is defined as the force experienced by a unit positive charge placed at the point.
- The electric field intensity is a vector quantity. electric field due to a positive charge is always away from the charge and that due to to a negative charge is always towards the charge.
- In an electric field E a charge Q experiences a force F= Q.E. if charge is positive than force is directed to the direction of field while if charge is negative force acts on it in the opposite direction of a field .
- so, if a positive charge is displaced against the electric field in which it was situated then work will be done by the electric field on the charge.
