Answer:
If we want to increase this force, we can increase the mass of the objects, but it is more effective to reduce the distance between them.
Step-by-step explanation:
The gravitational force exerted between two bodies depends on the distance between them and the mass of each of them. The formula is as follows:
= -G *

: Gravitational force.
G: Universal gravitation constant.
M and m: Masses of the interacting bodies.
r: Distance separating the bodies.
We observe that if M or m increases,
also increases. On the other hand, if r decreases, this causes
to increase as well.
Have a nice day!
