Question
If suddenly the gravitational force between the Earth and a satellite revolving around it becomes zero, what will happen?
- The satellite will move tangentially and escape away from its orbit.
- The satellite will continue to move in its orbit with the same velocity.
- The satellite will become stationary in its orbit.
- The satellite will move towards the Earth.
Hint:
The orbit of the satellite is due to the gravitational pull of the Earth.
The correct answer is: The satellite will move tangentially and escape away from its orbit.
The satellite was moving in its orbit since there was a force of attraction acting on the satellite in the form of the gravitational pull of the Earth. in the absence of this gravitational force, the force of attraction will be lost and the satellite will be unable to maintain its orbit and continue to move in a straight path with the same speed as was before the gravitational pull was lost. Hence, the satellite will move tangentially away from its orbit.
