A charge q1 = +4.0nC experiences a force of 3*10^-5N to the east when placed in an electric field. If the charged is replaced by another, q2 = -12nC, what will be the magnitude and direction of the force on the charge at that position?

    \[F=Eq\] therefore force is proportional to charge. \[F ^{'}=Fq ^{'}/q\] where \[F=3*10^{-5},q=4nc , q ^{'}=-12nc\] \[F ^{'}=-9*10^{-5}N\] -ve sign indicates force in west direction
