Explanation:
Detailed explanation-1: -Expert-Verified Answer Here, it interesting to notice that gravitational force between two bodies if 10 kg and 20 kg whuch are 5 m appart is 5.34 × 10^(-10 ). Such gravitational force is so small and thus is negligible.
Detailed explanation-2: -Gravitatonal force of attraction, F=GMmr2=6.67×10−11×10×10(0.1)2=6.67×10−1N.
Detailed explanation-3: -The gravitational force depends up on the product of the masses. So, the gravitational force would be maximum if the product of the masses is maximum. This quantity needs to be maximized. x = 5 kg for maximum gravitational force.
