NEET Physics Universal Law of Gravitation MCQ Question
If the gravitational force between two objects is 200 N when they are 5 m apart, what will be the force when the distance is reduced to 2 m, assuming the masses remain unchanged?
1250 N
500 N
800 N
1000 N
Correct Answer
Detailed Explanation
According to the Universal Law of Gravitation, the force is inversely proportional to the square of the distance between the objects. Reducing the distance from 5 m to 2 m increases the force by a factor of (5/2)^2, resulting in 200 N * (25/4) = 1250 N.
