Let force F, length L and time T be taken as fundamental units, then what will be the dimensional formula for mass?

A

`[FL^(-1)T^2]`

B

`[FLT^(-2)]`

C

`[FL^(-1)T^(-1)]`

D

`[FL^5T^2]`

Text Solution

Verified by Experts

The correct Answer is:
A
By second law of motion `F = ma " So, " m= F/a`
By principle of homogeneity `[m] = [F/a] =F^1/(L^1T^(-2)) =F^1L^(-1)T^2`
