Question

let the distance between two bodies be 'r'. Force of gravitation between two bodies varies with
(a) r^2
(b) r
(c) 1/r^2
(d) 1/r

Answer 1

Gravitational force between two bodies is inversely proportional to square of distance between them.
F ∝ 1/r^2

∴ (c) is correct option

Answer 2

let the distance between two bodies be 'r'. Force of gravitation between two bodies varies with (c) $1/r^{2}$

Explanation:

• Gravity, or gravity, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to each other.
• On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans.
• Newton's law of universal gravitation usually states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and the square of the distance between their centers. is inversely proportional.
• $F = G (m_{1} m_{2} )/ r^{2}$
• where G = gravitational constant
• $m_{1} and m_{2}$ are masses of the bodies.
• r  =  distance between the two bodies.
