Answer #1

Given: Position of q2 , Xa = 5m Solution The position of chargeg where the net force is zero, can be find as follows K is the common element in both sides. Hence they cancel with each other 213 21 Taking square root on both sides, 5-х 21 0.378 5-x= 0.378x 5 0.378x+x 5= 1.378x

1.378 x= 3.628772
