PhysicsEasysingle choice

A mass $M$ is split into two parts $m$ and $(M - m)$ , which are then separated by a certain distance. The ratio $m : M$ which maximizes the gravitational force between the parts is

Options:

Answer:

Solution:

$F = \frac{G m (M - m)}{x^{2}};$ For maxima,

$\frac{d F}{d m} = \frac{G}{x^{2}} (M - 2 m) = 0$

or $\frac{m}{M} = \frac{1}{2}$
