The dimensions of kinetic energy is :

A

`[M ^(2) L ^(2) T ^(1)]`

B

`[M ^(1) L ^(2) T ^(1)]`

C

`[M ^(1) L ^(2) T ^(-2)]`

D

`[M ^(1) L ^(2) T ^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
C
`KE = (1)/(2) mv ^(2)`
`therefore [ KE] = [M] [LT ^(-1) ] ^(2) = [ML ^(2) T ^(-2)]`
