If energy (E), velcocity (V) and time (T) were chosen as fundamental physical quantities for measurement, then the dimensional formula for mass will be

A

`[E^(1) V^(2)T^(1)]`

B

`[E^(2)V^(-2)T^(0)]`

C

`[E^(1)V^(-2)T^(0)]`

D

`[E^(-1)V^(2)T^(1)]`

Text Solution

Verified by Experts

The correct Answer is:
C

`because ` Kinetic energy = `(1)/(2) mV^(2)`
`therefore [m] = [(E)/(V^(2))] = [E^(1)V^(-2)T^(0)]`
