Question

How much is the range of gravitational force?name the messenger particle of this force?

Answer 1

The range of gravitational force is infinite.

Answer 2

Explanation:

As others have mentioned here -- correctly, of course -- there's no limit to the range of any object's gravitational influence. However, there is the concept of a sphere of influence, also known as a Hill sphere. In the case of the Earth, the figure comes out to about 1.5 million kilometers.

The hypothetical gravitational quantum or particle , the graviton, is the messenger particle for gravity. The messenger particles for the weak force are W-plus, W-minus, and Z-zero. The "plus" refers to the W's charge, which is positive
