Question

Which of the following is/are correct?

• A. Gravitational force can also act in vacuum.
• B. Gravitational force is independent of medium and it is the responsible for all the phenomena of nature like the moon around the Earth, the Earth around the Sun, our binding with the Earth etc.
• C. Newton was unable to discover the cause of gravitational force.
• D. All of these.

Answer 1

Answer: (A), (B)

The correct options are
A

Gravitational force can also act in vacuum.

B

Gravitational force is independent of medium and it is the responsible for all the phenomena of nature like the moon around the Earth, the Earth around the Sun, our binding with the Earth etc.

The Sun and the Earth are in the vacuum and Earth revolves around the Sun. The force that is responsible for this motion is the gravitational force of attraction. So, gravitational force can act through the vacuum.

The gravitational force is independent of medium.

The force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
