Question

The gravitational force between two objects is 2N. What will be the gravitational force between these two objects if the distance between them becomes double ?

Answer 1

Answer:

Explanation:

Gravitational force between two objects is inversely proportional to square of the distance between the two objects.So,force becomes one fourth of original force.

Hence, answer is 2/4=0.5N, hope you understood

Answer 2

The gravitational force between two objects is inversely proportional to the square of the distance between the objects.

So, force becomes one-fourth of the original force.

Hence, answer is 2/4 = 0.5N.

Hence,

Using the formula g = ( G$M_{m}$ ) / R², we get

g1 = G$M_{m}$ / $R^{2}$ ...  (1)

g2 = G$M_{m}$ / ( $2R^{2}$ )

     = G$M_{m}$ / ( $4R^{2}$ )

g2 = 2/4

     = 0.5N
