Question

state newtons law of gravitation. what will be the value of gravitational force between them,if masses of both are doubled and the distance between them is halved?​

Answer 1

Answer:

Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

the force in your hypothetical case will be 16 times

Explanation:

16 times because

F=GmM/r*r

for halving radius, F multiplies 4 times. for doubling each mass, ie m and M become 2m, and 2M,   F finally becomes

F'= G(2m)(2M)(4)/r^2

=>F'=16GmM/r^2

=>F'=16F

Answer 2

Explanation:

every particle attract each other force which is directly proportional to the their masses and inversely proportional to the square of distance between their center...
