Two point charge `Q_(a)` and `Q_(b)` are positional at point A and B. The field strenght to the right of charge `Q_(b)` 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=21 cm`.  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V03_C01_E01_079_Q01.png" width="80%"  (a) Find the sign of the charges.  (b) Find the ration between the absolute value of charge `Q_(a)` and `Q_(b)`.  (c ) Find the coordinate x of the point where the field strenght is maximum.
