If suddenly the gravitational force of attraction between earth and a satellite revolving around it become zero, then the satellite will

If the gravitational force acting on a satellite were to suddenly become zero, the satellite would no longer experience the centripetal force required to maintain its curved orbital path. As a result, it would move in a straight line tangent to its original orbit, maintaining the velocity it had at the moment the gravitational force ceased.
This is due to the principle of inertia, where an object in motion continues in its state of motion unless acted upon by an external force. Therefore, without gravity to keep it in orbit, the satellite would follow a straight-line trajectory in the direction of its velocity.
