Explanation:
The satellite is held in orbit because of two forces : gravitational force and centrifugal force. When the gravitational force disappears, there is no force to hold it in orbit. So it moves in the direction of its velocity, which is tangential to the circular path it was following earlier.
An orbiting satellite is close enough to be acted upon by Earth's gravity. This force is constantly pulling the satellite in toward the center of the earth – it is a centripetal force and causes a centripetal acceleration. At this height, however, Earth's gravity is only about 8.7 m/s2.
