Question

Mark out the correct statement related to Newton’s law of universal gravitation.

• A. It is valid only for particles and spherically bodies.
• B. It is an action-reaction pair.
• C. It is valid for interatomic distances also.
• D. It is a very strong force.

Answer 1

Answer: (A), (B), (C)

It is valid for interatomic distances also.

Explanation

1. Every particle in the universe attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers, according to Newton's law of universal gravitation.
2. Newton’s law of universal gravitation is valid only for particles and spherical bodies.
3. It is an action-reaction pair.
4. It is valid for interatomic distances also.

Hence, the correct answers are options (a), (b), and (c ).
