An artificial satellite orbiting around the Earth does not fall down. ...
An artificial satellite moving round the Earth in a circular orbit possesses an acceleration which is “constant” in magnitude but “changing in direction”. An artificial satellite revolves round the earth under centripetal acceleration. By the launch rocket, immediately before the satellite is established in the predetermined orbit, the speed given to it is 30, 000 km/hr. The speed must be great enough so gravity doesn’t bring the satellite back to Earth, but not so great that the satellite escapes gravity out into space. This means that the speed, which is provided by the rocket is the source of the centrifugal force, and the attraction of the earth holds it from moving away from this centrifugal force.

An artificial satellite orbiting around the Earth does not fall down. ...
The correct answer is option 'D': The attraction of Earth provides the necessary acceleration for the motion of an artificial satellite orbiting around the Earth. Let's understand why this is the correct answer.
Gravity and Satellite Motion:
- The force of gravity is responsible for the motion of satellites orbiting around the Earth. This force attracts the satellite towards the Earth, causing it to constantly fall towards the Earth.
- However, the satellite is also moving forward with sufficient speed, which allows it to continuously fall towards the Earth while maintaining a circular or elliptical orbit.
- This combination of the satellite's forward velocity and the gravitational force acting towards the center of the Earth creates a balanced motion, resulting in a stable orbit.
Explanation of Option 'A' and 'B':
- Option 'A' states that the attraction of Earth does not exist at such a distance. This is incorrect because the force of gravity exists everywhere in the universe, including all distances around the Earth.
- Option 'B' suggests that the attraction of the Moon neutralizes the Earth's attraction. While the Moon's gravity does have an effect on the motion of satellites, it is negligible compared to the gravitational force of the Earth. Hence, this option is also incorrect.
Explanation of Option 'C' and 'D':
- Option 'C' states that the attraction of Earth provides the necessary speed for steady motion. While gravity does affect the speed of a satellite, it does not provide the necessary speed for steady motion. The satellite must be launched with sufficient velocity to achieve and maintain its desired orbit.
- Option 'D' states that the attraction of Earth provides the necessary acceleration for its motion. This is the correct answer because the gravitational force of the Earth provides the necessary centripetal acceleration that keeps the satellite in its orbit.
- The centripetal acceleration is directed towards the center of the Earth, causing the satellite to continuously change its direction and stay in orbit. This acceleration is provided by the gravitational force acting on the satellite.
In conclusion, the correct answer is option 'D' because the attraction of Earth provides the necessary acceleration for the motion of an artificial satellite orbiting around the Earth.
