Question

State Newton's universal law of gravitation . Derive a mathematical expression for the Newton's law of gravitation

Answer 1

Newtons law of universal gravitationstates that a particle attracts other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Answer 2

Newton's law of gravitation is also known as universal law of gravitation according to this law every object in this universe attract each other and the force acting between them is directly proportional to product of masses of objects and inversely proportional to square of distance between them.

D= distance

F ∝m1m2 (1)

F∝1/d^2. (2)

F∝m1m2/d^2

F= G m1 m2 / d^2

G=constant
