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

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
