Question
Suppose a quantity x can be dimensionally represented in terms of M, L and T, that is, `[ x ] = M^a L^b T^c`. The quantity mass
Options
can always be dimensionally represented in terms of L, T and x,
can never be dimensionally represented in terms of L, T and x,
may be represented in terms of L, T and x if a = 0,
may be represented in terms of L, T and x if a ≠ 0
Solution
may be represented in terms of L, T and x if a ≠ 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.
