General KnowledgePhysics
- Aremain same
- Bincrease by two times
- Cdecrease by two times
- Ddecrease by four times
Explanation
Newton's law of gravitation states that the force varies inversely with the square of the distance (F proportional to 1/r-squared). Doubling the distance therefore makes the force one-fourth of its original value. The correct answer is that it decreases by four times.
