Question

The gravitational force cause?

• A. Tides
• B. None of them
• C. Motion of moon
• D. Both A and C

Answer 1

The correct option is D

Both A and C

Gravitational Force:

1. The gravitational force is the universal force of attraction that acts between objects.
2. A gravitational force is a conservative force.
3. A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the path taken.

Explanation for Correct answer:

Option D: Both A and C

Option (C) : Motion of moon

1. The moon moves in a circular orbit around the Earth. In reality, the orbit is elliptical rather than circular.
2. When a body moves in a circular motion, a centripetal force acts on it, and in the case of the moon's motion around the earth, gravitational force provides the centripetal force.
3. Hence, option C is correct.

Option (A) : Tides

1. Tides and ocean currents are also caused by the moon's gravitational pull.
2. The moon produces tidal force, which is responsible for high and low tides.
3. Option A is also correct.

Thus, Option D is the correct answer.
