Questions  

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

a
Same as that of pressure
b
Same as that of work
c
That of momentum
d
Same as that of latent heat

detailed solution

Correct option is D

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