The quantities `A and B` are related by the relation `A//B = m`, where `m` is the linear mass density and `A` is the force , the dimensions of `B` will be

Options

A. pressure
B. work
C. latent heat
D. None of these

Answer

C

Explanation

`m=`linear density`=`mass per unit length`=[(M)/(L)]`
`A=`force`=[MLT^-2]` because `[B]=([A])/([m])=([MLT^-2])/([ML^-1])=[L^2T^-2]`
This is same dimesnsion as than of latent heat
