If the distance between two objects is increased, the gravitational force will .
decrease
decrease by the distance squared
increase
increase by the distance squared

Decrease by the distance squared

Explanation:

Gravitation formula:

where

'F' is the force of attraction between the two bodies (Gravitational force),

'G' is the universal gravitational constant,

'M' is the mass of the first object,

'm' is the mass of the second object and

'r'  is the distance between the centers of each object.

Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared

it is no longer used clinically
