Suppose a quantity can be dimensionally represented in terms M , L and T , that is y = M a L b T c . The quantity mass

Options

  1. Amaybe represented in terms of L , T and y if a = 0
  2. Bmaybe represented in terms of L , T and y if a ≠ 0
  3. CCan always be dimensionally represented in terms of L , T and y
  4. DCan never be dimensionally represented in terms of L , T and y

Correct answer

B. maybe represented in terms of L , T and y if a ≠ 0

Step-by-step solution

M= y 1 a . L − b a . T − c a where a should not be zero.
