- #3Suppose 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: dAns : (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.
