### Gravitation Quiz Questions and Answers

According to the universal law of gravitation, the force of attraction between bodies is directly proportional to the product of their masses is inversely proportional to the square of the distance between them. Gravitational force is a central force and conservative in nature. So take this quiz and know about gravitation.
