    The dimensions ML-1 T-2 may correspond to
    -(a) work done by a force
    (b) linear momentum
    (c) pressure
    (d) energy per unit volume.
    digAnsr:   c,d
    Ans : (c) pressure
    (d) energy per unit volume
    [Work done] = [ML2T-2]
    [Linear momentum] = [MLT-1]
    [Pressure] = [ML-1 T-2]
    [Energy per unit volume] = [ML-1 T-2]
    From the above, we can see that pressure and energy per unit volume have the same dimension, i.e., ML-1 T-2.
