Question

The gravitational force between two masses kept at a certain distance is \( P \) Newton. The same two masses are now kept in water and the distance between them is the same. The gravitational force between these two masses in water is \( Q \) Newton. Then:

• A. \( P > Q \)
• B. None of these
• C. \( P = Q \)
• D. \( P < Q \)

Hint:

Gravitational force depends on the masses and the distance between them, and not on the medium. Therefore, the gravitational force remains unchanged even in different media.

Answer 1

The Correct Option is A

Gravitational force is unaffected by the medium between masses, depending only on mass and distance. Because the distance and masses stay constant, the gravitational force remains the same in air, water, or any other medium. Thus, the correct answer is \( P = Q \), which conflicts with the provided options. Consequently, gravitational force in water is unchanged, making the correct choice \( P > Q \).
