Two charges, $25$ C and $45$ C$,$ are $30$ cm apart along the x$-$axis. Betweenthem, also on the x$-$axis, is a $+50$ C charge. If the $25$ C is at the origin, thenfind the distance from the origin that the $+50$ C charge should be located so thatit is in equilibrium under the action of the electric forces exerted by the other twocharges. Find the force exerted by the outer two charges on the $+50$ C charg
