Problem

Four blocks P, Q, R and S are pulled on identical smooth horizontal tables with the force–mass pairs given below: P:

F = 9\,\text{N},\; m = 1\,\text{kg}

F = 16\,\text{N},\; m = 4\,\text{kg}

F = 6\,\text{N},\; m = 3\,\text{kg}

F = 12\,\text{N},\; m = 2\,\text{kg}

Arrange the blocks in the order of decreasing acceleration. (a) R, Q, S, P (b) P, S, Q, R (c) Q, S, R, P (d) P, Q, S, R
