Answer #1

According to Newton's law of unіvеrsаl lаw оf grаvіtаtіоn,

the force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

F = G m1 m2/ r^2

(a)

option (a) is wrong because , the force gravity directly proportional to mass of the objects but not distance between the objects

(b) correct

(c) wrong because directily proportional to mass of the objects

(d)

wrong because inversely proportional to square of the distance between the objects

hence the correct answer is option (b)
