1.

Two point - like chargesQ_(1) and Q_(2) are positioned at point 1 and 2 respectively. The field intensity to the right of the charge Q_(3) on the line that passes through the two charges varies according to a law that is represented schematically in the figure. The field intensity is assumed to be positive if its direction with the positive direction on the x-axis. The distance between the charges is l, then which of the folllowing is true

Answer»

`Q_(1)` is positive charge while `Q_(2)` is negative charge
The RATIO of the absoulte value of the CHARGES `|(Q_(1))/(Q_(2))|((a+l)/(a))^(2)`
The value of b, where the field intensity is maximum is `b = (l)/(((l + a)/(2a))^(2//3)-1)`
The valueof b , where the FILED intesityis maximum is

Answer :A::B::D
