Question

AS YOU CAN SEE THIS WHAT IS GIVEN IN FIGURE..!!
SO PLEASE MAKE A FORMULAE ACCORDING TO THIS AS WHAT IT SAYS THAT FORCE IS DIRECTLY PROPOTIONAL TO PRODUCT OF THEIR MASSES AND SQUARE OF INVERSELY PROPORTIONAL TO SQUARE OF DISTANCE BETWEEN THEM...!!
so please make a formulae according to this and make derivation please..!!​

Answer 1

Answer:

F = G M1*M2 / R^2

Explanation:

Let the mass of the two bodies be 'M1' and 'M2' and the distance between them be 'R'

Thus ,

According to the question ,

Force (F) is directly proportional to (M1*M2) ---> 1

Also,

Force (F) is inversely proportional to (R^2) -----> 2

Thus ,

On combining 1 and 2 ,

F = M1*M2 / R^2

Note : We cannot use '=' symbol unless we add a proportionality constant  

Therefore ,

The proportionality constant becomes 'G' whose value is 6.67 * 10^-11 Nm^2/kg^2 . 'G' is also known as Gravitational Constant

Thus ,

The formula becomes F = G M1*M2 / R^2

Hope it helps
