Point charge
moves from point
to point
along the path
(figure shown) in a uniform electric field
pointing coparallel to the positive direction of the
axis. The coordinates of the points
and
are
and
respectively. The work done by the field in the above process is given by the expression

Text Solution
Verified by ExpertsThe correct answer is:
B
As electric field is a conservative field Hence the work done does not depend on path

∴ ∴

= Fb cos 90 o + Fa cos 180 o = 0 + qEa (– 1)= – qEa
