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
Same as that of pressure
Same as that of work
That of momentum
Same as that of latent heat
AB=m,B=Am= Force Linear density =MLT−2ML−1∴ B=M0L2T−2 Latent heat = Heat energy Mass =ML2T−2M=M0L2T−2
Thus, B has same dimensions as that of latent heat.
