An unknown quantity `''alpha''` is expressed as `alpha = (2ma)/(beta) log(1+(2betal)/(ma))` where m = mass, a = acceleration `l` = length, The unit of `alpha` should be

A

meter

B

m/s

C

`m//s^(2)`

D

`s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
`[(2 beta l)/(ma)] = M^(0)L^(0)T^(0)`
`[(beta)/(ma)] = [(1)/(l)]`
`[alpha] = [(ma)/(beta)] = [l]`
