Question

prove that:the force is inversely proportional t the square of the distance between sun and planet​

Answer 1

Explanation:

According to Newton law of Gravation

Force between any two bodies is directly proportioanl to the mass of the object and inversely proportioanl to the square of the distance it can be represented by this -

Force b/t any two bodies

F directly proportioanl = Mm

and

Distance b/t them

F inversly proportional to the square of the distsnce = 1/r²

Now add Gravational Constant then we have

F = GMm/r²

G is Newton Gravational constant that have constant value 6.67 Nm²/kg²

Easy Example for that it is not physics force but it is something like that

Imagine

A Ball Placed on a blanket and it wrap the blanked the area of wrapeing is force if you a ball at centre and a another ball far from other ball on blanket

the ball doesn't feel any wrap of Ball which is in centre and thats Gravity

Look like Einstein General Relativity

Some extra fact : -

Newton is wrong about gravity

Albert Einstein is right about Gravity
