The dimensional formula of latent heat is identical to that of


ANSWER

gravitational potential


SOLUTION
Latent heat is given by:
$$Q=mL$$
$$\Rightarrow L=\displaystyle \frac {Q}{m}$$ i.e Energy per unit mass.
a) internal energy has the units of energy
b) angular momentum has the units Joule-sec, i.e Energy.second
c) Gravitational potential is the potential energy per unit mass, i.e Energy per mass
d) Electric potential is the potential energy per unit charge.
