The field strenght to the right of charge Qb on the line that passes therough the two charges varies according to a law represented schematically in fig. (without employing a definite scale). The field strength is assumed to be positive if its direction coincedes with the positive direction of the x-axis. The distance between the charges is l=21cm .

respectively. Find the position of the point where the net field is zero due to thses charges. The positions of two point charges q1 and q2 are →r1 and →r2
