Vedclass · Answer

(B) According to Newton's first law of motion,an object in motion will continue to move in a straight line with constant velocity unless acted upon by an external force.In a circular orbit,the gravitational force provides the necessary centripetal force to keep the satellite moving in a circle.If the gravitational force suddenly disappears,there is no longer any centripetal force to change the direction of the satellite's velocity.Therefore,due to the inertia of direction,the satellite will continue to move in a straight line along the direction of its velocity at that instant.Since the velocity vector is always tangent to the circular path,the satellite will move with velocity $v$ tangentially to the original orbit.

$A$ satellite of the earth is revolving in a circular orbit with a uniform speed $v$. If the gravitational force suddenly disappears,the satellite will
