Find the gravitational force between two stones, each of mass $2 \,kg$ and separated by a distance $1 \,m$ in vacuum.

$A$ system consists of three particles each of mass $m_1$ placed at the corners of an equilateral triangle of side $\frac{L}{3}$. $A$ particle of mass $m_2$ is placed at the midpoint of any one side of the triangle. Due to the system of particles,the force acting on $m_2$ is

Which of the following is incorrect about the gravitational force between two bodies?

$A$ large number of identical point masses $m$ are placed along the $x$-axis at $x = 0, 1, 2, 4, 8, \dots$ units. The magnitude of the total gravitational force on the mass at the origin $(x = 0)$ will be:

Two point objects of mass $2x$ and $3x$ are separated by a distance $r$. Keeping the distance fixed,how much mass should be transferred from $3x$ to $2x$,so that the gravitational force between them becomes maximum?

Explain the principle of superposition for gravitational force.
