Q1.)CALCULATE THE WORK DONE TO DISSOSIATE THE SYSTEM OF THREE CHARGES PLACED ON THE VERTICES OF THE TRIANGLE ABC

HERE q=1.6 * 10-10 C

all side of 10cm ,A=q ,B=2q,C=-4q

Let qa qb qc be the charge on the corners A, B , C.

Work done in dissociate this charge configuration will be negative of the  potential energy of the system.

U =- kqaqbAB + kqbqcBC  + kqaqcACAb = BC = AC = 10 cm

Work done can be calculated using the above relation.
