Question

Two points objects of mass 2x and 3x are separated by distance r. distance fixed, how much mass should be transferred from 7x to 9x, so that gravitational force become maximum

Answer 1

Explanation:

The gravitational force will be maximum when 0.5x mass will be transferred from 3x to 2x. keeping r constant, the force depends upon the product of two masses. According to the principle of mathematics Product of any two numbers is maximum when they are equal to each other.
