The dimension of mass is zero in which of the following physical quantities?
(A) Gravitational potential
(B) Latent heat
(C) Specific heat capacity
(D) All of the above

Hint
The gravitational potential at a point in a gravitational field is the work done per unit mass that would have to be done by some externally applied force to bring a massive object to that point from some defined position of zero potential, usually infinity .

Complete step by step answer
The dimension of the gravitational potential = $ [\dfrac{{Force}}{{Mass}} \times r] = [\dfrac{{{M^1}{L^2}{T^{ - 2}}}}{{{M^1}}}] = [{M^0}{L^2}{T^{ - 2}}] $ ......(1)
Now, the latent heat is an energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Dimension of the latent heat is, = $ [\dfrac{{Energy}}{{Mass}}] = [\dfrac{{{M^1}{L^2}{T^{ - 2}}}}{M}] = [{L^2}{T^{ - 2}}] $ ......(2)
Now, the dimension of the specific heat capacity is = $ [\dfrac{{Energy}}{{Mass \times temp}}] = [\dfrac{{{M^1}{L^2}{T^{ - 2}}}}{{{M^1}{K^1}}}] = [{L^2}{T^{ - 2}}{K^{ - 1}}] $ .....(3)
So, the dimension of mass is zero in every physical quantity in the option.

Note
The heat capacity and the specific heat are related by $C=cm$ or $c=C/m$. The mass $m$, specific heat $c$, change in temperature $ΔT$, and heat added (or subtracted) $Q$ are related by the equation: $Q=mcΔT$. Values of specific heat are dependent on the properties and phase of a given substance.
