Two charges charge +q are kept d distence away. M

Question

Two charges charge +q are kept d distence away. Mass of charges 2M and 3M. They are released from rest. Find time when separation becomes 3d.

Vikas TU · Accepted Answer

0 + 0 + q(kq/d) = 0.5*2M*v1^2 + 0.5*3M*v2^2 + q(kq/3d) 0.5*2M*v1^2 + 0.5*3M*v2^2 = kq^2/d – kq^2/3d 0.5*M(2v1^2) + 0.5*M(3v2^2) = 2kq^2/3d ….......................(1) Momentum conserved. 0 + 0 = 2M*v1 + 3M*v2or2v1 + 3v2 = 0 …..............(2) solve eqns. (1) and (2)and get v1 and v2. calculate Time = 3d/v1or v2 (take any speed).
