The velocity of a moving particle depend...

The velocity of a moving particle depends upon time t as v `= at+(b)/(t+c)`. Then dimensional formula for b is-

A

`[M^(0)L^(0)T^(0)]`

B

`[M^(0)L^(1)T^(0)]`

C

`[M^(0)L^(1)T^(-1)]`

D

`[M^(0)L^(1)T^(-2)]`

Text Solution

Verified by Experts

The correct Answer is:
B
`[(b)/(t)]=[v]`
`[b] =LT^(-1).T=L`
