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

Options

A. continue to move speed `v` along the original orbit
B. move with the velocity `v` tangentially to the original orbit
C. fall downward with increasing velocity
D. ultimately come to rest somewhere on the original orbit

Answer

B

Explanation

In circular path, if necessary centripetal force disappears, then the body moves with velocity `v` tangentially to original orbit tangential path.
