Answer 1

Answer:

it will help u if s pls mark me as brainlist

Answer 2

• F is the gravitational force between two bodies
• m1 is the mass of one object
• m2 is the mass of the second object
• r is the distance between the centers of two objects
• G is the Universal Gravitation Constant.

According to the universal law of gravitation:

• F is directly proportional to product of masses of the 2 bodies
• F is inversely proportional to the square of distance of seperation.

Therefore, on combining both the equations above

• F=G (m1*m2)/r^2.

*G is a constant of proportionality which is known as Universal Gravitation Constant.
