Fall down with increasing velocity

Ultimately come to rest somewhere on the original orbit

Detailed explanation-1: -The satellite is revolving around earth because the centripetal force is balanced by earth’s gravitational pull. If the gravitational pull disappears, the satellite free of centripetal force. So, it will travel with its instantaneous velocity i.e. in the direction tangential to the circular path.
Detailed explanation-2: -Satellite always is attracted by a gravitational force and hence is a freely falling body. It is moving with a constant speed. The gravitational force acts towards the center of the earth which provides the necessary centripetal force to keep satellite in a circular orbit.
Detailed explanation-3: -Yes, the motion of a satellite around the earth in a circular orbit is accelerated. Acceleration depends on velocity. Velocity has magnitude and direction. Satellite is moving with uniform speed but its direction of motion is changing at each point.
Detailed explanation-4: -Orbital velocity, 4v0=Re+hGMe 6380+2620(6. 67×10−11)(6×1024) =6. 67km/secTimeperiodofrevolution, T=2v0(Re+h)=6.
Detailed explanation-5: -The Short Answer: Gravity-combined with the satellite’s momentum from its launch into space-cause the satellite to go into orbit above Earth, instead of falling back down to the ground.
Detailed explanation-6: -The period, speed and acceleration of a satellite are only dependent upon the radius of orbit and the mass of the central body that the satellite is orbiting.
