JEE Main & Advanced Physics Gravitation / गुरुत्वाकर्षण JEE PYQ-Gravitation

  • question_answer
    If suddenly the gravitational force of attraction between earth and a satellite revolving around it becomes zero, then the satellite will                                                                                            [AIEEE 2002] 

    A)  continue to move in its orbit with same velocity

    B)  move tangentially to the original orbit with the same velocity

    C)  become stationary in its orbit

    D)  move towards the earth

    Correct Answer: B

    Solution :

     When gravitational force becomes zero, then centripetal force required cannot be provided. So, the satellite will move with the velocity as it has at the instant when gravitational force becomes zero, i.e., it moves tangentially to the original orbit due to inertia.
