  • a)
    Continue to move with velocity ν along the original orbit
  • b)
    Move with a velocity ν, trangentially to the original orbit
  • c)
    Fall down with increasing velocity
  • d)
    Ultimately come to rest somewhere on the original orbit
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Initial Scenario:
- The satellite is revolving in a circular orbit around the Earth with a uniform speed ν under the influence of gravitational force.

Impact of gravitational force disappearance:
- When the gravitational force suddenly disappears, the satellite will no longer experience the centripetal force required to keep it in its circular orbit.

Effect on the satellite:
- The satellite will continue to move with the same velocity ν but in a tangential direction to its original orbit.
- This motion is governed by Newton's first law of motion, which states that an object in motion will continue to move with a constant velocity unless acted upon by an external force.

Reasoning:
- As there is no force acting on the satellite after the disappearance of the gravitational force, it will move in a straight line tangentially to its original orbit with the same speed.
- The satellite will not fall down with increasing velocity or come to rest somewhere on the original orbit as there are no forces causing these motions.
Therefore, the correct answer is option B, the satellite will move with a velocity ν, tangentially to the original orbit.
