Two points like charges Q_(A) and Q_(B) are positioned at points a and B (see figure). The electric field strength to the right of charge Q_(B) on the line that passes through the two charges varies according to a law that is represented schematically in Figure below accompaanying the problem without employing a definite scale. Assume electric field to be positive if its direct ion coincides with (the positive direction on the x-axis. THe distance between the charges is l.
