- \( \mathrm{\frac{T}{M}} \)
- \( \mathrm{\frac{L^{2}}{TM}} \)
- \( \mathrm{\frac{TM}{L^{2}}} \)
- \( \mathrm{\frac{M}{L^{2}T}} \)

Correct Option: (A)

\[ \mathrm{A = BC} \]

\[ \mathrm{B = \frac{A}{C}} \]

\[ \mathrm{B = \frac{L/M}{L/T}} \]

\[ \mathrm{B = \frac{T}{M}} \]

## Suppose A = BC, where A has the dimension of L/M and C has the dimension of L/T. Then B has the dimension of

Suppose A = BC, where A has the dimension of L/M and C has the dimension of L/T. Then B has the dimension of T/M.

### Helping Concept

\[ \mathrm{A = BC} \]

\[ \mathrm{B = \frac{A}{C}} \]

\[ \mathrm{B = \frac{L/M}{L/T}} \]

\[ \mathrm{B = \frac{T}{M}} \]

Therefore the correct option is (A).
