Two particle A and B start moving due to their mutual interaction only. If at any tiem \'t\', `vec(a)_(A)` and `vec(a)_(B)` are their respective accelerations, `vec(v)_(A)` and `vec(v)_(B)` are their respective velocities, and upto that time `W_(A)` and `W_(B)` are the work done on A and B respectively by the mutual force, `m_(A)` and `m_(B)` are their masses respectively, then which of the following is alwys correct.
