Question

two particles A nad B are observed at t=0 seconds then what is the velocity of A with respect to B at t=2 seconds wil be​

Answer 1

Answer:

Here A and B are may be rest or in motion at t=0...there nothing is mentioned above whether the two particles are moving...so at t=2 also they will be in rest...so at any movement the velocity of A is 0 w.r.t B in this case....
