a positive charge q is carried slowly from a point x to point y in an electric field of point charge +Q. the work done by external force is
Dear student,
work done by external agent = cahnge in potential energy
= (PE)final - (PE)initial
= (KQq/r2)- (KQq/r1)
where r1 and r2 are the separation between charges
put value of them in term of x, y from daigram you have
Regards.
