Some important remarks may be made here:
(i)
From Eq (1 8), we can infer that if q is unity, the electric field due to
a charge Q is numerically equal to the force exerted by it Thus, the
electric field due to a charge Q at a point in space may be defined
as the force that a unit positive charge would experience if placed
