Time (T), velocity (3) and angular momentum (h) are chosen as fundamental quantities instead of mass, length and time. In terms of these, the dimensions of mass would be

A

`[M]=[C^(-1)h]`

B

`[M]=[T^(-1)C^(2)h]`

C

`[M]=[T^(-1)C^(-2)h^(-1)]`

D

`[M]=[C^(-2)h]`

Text Solution

Verified by Experts

The correct Answer is:
A

Let mass, related as `M prop T^(x)C^(y)h^(z)`
`M^(1)L^(0)T^(0)=(T.)^(x)(L^(1)T^(-1))^(y)(M^(1)L^(1))(T^(-1))^(z)`
`M^(1)L^(0)T^(0)=M^(z)L^(y+z)+T^(x-y-z)`
`z=1, y+z=0, y=-1" "x-y-z=0" "x=0`
`M=[C^(-1)h]`
