Gravitational force between two point masses m1
and m2
placed at a distance r is given by
1 2
Gm m F
= ; where G is an universal constant. An
object of mass M is divided into two parts, which
are placed at distance r. Find the mass of both parts
if gravitation force of attraction is maximum
between them.

  1. the product of two numbers is maximum when they are the same.
    Just as the area of a rectangle with a given perimeter is maximum when it is a square.

    and write the law as

    F = Gm1*m2/r^2

    if you want to be able to read it.
