Answer:
The force of universal gravitation between earth and all objects in it will be quadrupled
Explanation:
Newtons law of universal gravitation tell us the force of attraction between two bodies on the earth surface . This force is directly proportional to the product of the masses of the bodies and inversely proportional to their distance apart.
f is directly proportional to m1*m2
doubling these masses will be 2m1*2m2 = 4m1m2
if mas of earth is Me and mass of all objects is Mo
the f is proportional to Me*Mo
doubling the masses of the earth and all objects we have, 2Me*2Mo= 4MeMo
This means that doubling the masses of the earth and all objects on it will cause the force of gravitational attraction to be quadrupled.
