Question

State the universal law of gravitation.

• A. Everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.
• B. No body in this universe attracts other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.
• C. Everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the cube of distance between their centers.
• D. Everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of distance between their surfaces.

Answer 1

The correct option is A Everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.

The Law of Gravitation states that any two bodies attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centers.
$F=\frac{GMm}{R^2}$ where $G$ is the gravitation constant, $M$ and $m$ are the masses, and $R$ is the distance separating them.
