# Suppose a Quantity X Can Be Dimensionally Represented in Terms of M, L and T, that Is, [ X ] = M^A L^B T - Physics

MCQ

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.

Is there an error in this question or solution?
