Question

State the Universal law of Gravitation.

Answer 1

Newton's law of universal gravitation states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Every point mass attracts every single other point mass by a force pointing along the line intersecting both points.

F = $\frac{G{m}_1{m}_2}{r^2}$

$F_1$ = $F_2$ = $\frac{G{m}_1\times m_2}{r^2}$

where, F is the force between the masses, G is the gravitational constant, m₁ is the first mass, m₂ is the second mass, and r is the distance between the centre of masses.
