Question

Two charges, q1 and q2 , are located at the origin and at (0.40 m , 0), respectively.

Explanation / Answer

he charge Q3 must be placed at distance X from the origin such that k . Q1 . Q3 / X^2 = k . Q2 . Q3 / (55 - X )^2 since Q1 = Q2 ( 55 - X ) ^2 = X^2 55^2 - 110 X + X^2 = X^2 55/2 = X = 22.5 m If the charges ( Q1 and Q2) are unlike, then there is no place on the x axis where any third charge can be in equlibrium with the pair of charges.
