Obviously, take example that u have one thread in your hand with stone tied at one end and your moving it in vertical circular manner and if u suddenly leave the thread it will go in the direction tangentially to your arm here your hand force is equal to gravitation force but your hand plays centrifugal and gravitation plays centripetal.

Understanding the Satellite's Motion
When a satellite orbits the Earth, it is in a delicate balance of gravitational pull and its forward motion. The gravity of Earth provides the necessary centripetal force to keep the satellite in its circular path.
What Happens When Gravity Vanishes?
If the Earth's gravity were to suddenly vanish:
Direction of Motion
Since the satellite was moving in a circular orbit, its velocity vector is tangential to the orbit at the point of gravitational loss.
Conclusion
Thus, the correct answer to the question is option 'B':
- The satellite will start moving with velocity v in a direction tangential to the orbit.
This is consistent with Newton's first law of motion, which states that an object in motion will remain in motion in a straight line unless acted upon by an external force. Since there is no force acting on the satellite after gravity vanishes, it continues in a straight line at the same speed.
Key Takeaway
- The satellite does not fall towards the Earth or get lost in space; it simply travels tangentially at velocity v.
When a satellite orbits the Earth, it is in a delicate balance of gravitational pull and its forward motion. The gravity of Earth provides the necessary centripetal force to keep the satellite in its circular path.
What Happens When Gravity Vanishes?
If the Earth's gravity were to suddenly vanish:
- The satellite would no longer experience any gravitational force pulling it towards the Earth.
- It would retain its existing velocity (v) at that moment.
Direction of Motion
Since the satellite was moving in a circular orbit, its velocity vector is tangential to the orbit at the point of gravitational loss.
- With gravity gone, the satellite will no longer be constrained to follow a circular path.
- It will move in a straight line in the direction that it was traveling at the moment gravity ceased.
Conclusion
Thus, the correct answer to the question is option 'B':
- The satellite will start moving with velocity v in a direction tangential to the orbit.
This is consistent with Newton's first law of motion, which states that an object in motion will remain in motion in a straight line unless acted upon by an external force. Since there is no force acting on the satellite after gravity vanishes, it continues in a straight line at the same speed.
