Answer 1

There is only mass and not relativistic mass. Nearly all physicists who work with gravitational theory or with particle physics have abandoned the concept of relativistic mass because it produces confusion and adds nothing to the understanding of relativistic effects.

If we are talking about relativity, the gravitational theory that works is the general theory of relativity, and the idea of force doesn’t apply.

If you want to try to use ideas from the special theory along with Newton’s Law of Gravitation, the gravitational field is said to act only on mass. The gravitational force would then not depend on the motion of the object.
