    Suppose a quantity x can be dimensionally represented in terms of M, L and T, that is,
    [x]=``M^aL^bT^c``. The quantity mass
    -(a) can always be dimensionally represented in terms of L, T and x,
    (b) can never be dimensionally represented in terms of L, T and x,
    (c) may be represented in terms of L, T and x if a = 0,
    (d) may be represented in terms of L, T and x if
    a≠0.
    digAnsr:   d
    Ans : (d) may be represented in terms of L, T and x if `` a\ne 0``
    If a = 0, then we cannot represent mass dimensionally in terms of L, T and x, otherwise it can be represented in terms of L, T and x.
