Question

state the universal law of gravitation and derive its mathematical expression ​

Answer 1

Answer:

Newton's universal law of gravitation states that when two body are separated by a distance r, then both attract each other with a force which is directly proportional to the product of their masses(m1 and m2) and inversely proportional to the square of distance between them (r). This force is termed as gravitational force.

Mathematically, gravitational expression is

$f = Gm1m2 \div {r}^{2}$
