Question

31.Write the Equation for law of universal gravitation . What happens to the force between two

objects, if the mass of one object is doubled and the distance between the objects is reduced to

half ?​

Answer 1

F=GMm/r^2

mass of one object =2m

mass of another object = M

disatance /r=1/2=r/2

now according to equation F=G2Mm/r/2 ^2

it is equal to 4f
