Is there a gravitational force between antiparticles? For example, between two antiprotons. Do the antiprotons repluse each other?

3There's gravitational force to anything that has mass/energy/momentum. Also gravitational force is always attractive. – Gradient137 Nov 22 '18 at 22:34

Because antiparticles have mass, they will necessarily experience the attractive force of gravity. That force will be extremely tiny compared to the electrostatic force of repulsion between two antiprotons.
