Answer: The only force that acts between particles of helium gas is Vanderwaal forces.
Explanation:
When molecules are uncharged in nature but still combined together due to the dipole moment of elements then this force holding the molecules together is known as Vanderwaal forces.
This force is weak in nature.
For example, particles of helium gas has Vanderwaal force between its atoms.
Thus, we can conclude that the only force that acts between particles of helium gas is Vanderwaal forces.
