Test Preparation on Gravitation - III - Physics Test Series IIT JEE-2020

1.

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

1Continue to move with velocity v along the original orbit
2Move with a velocity v, tangentially to the original orbit
3Fall down with increasing velocity
4Ultimately come to rest somewhere on the original orbit

Due to inertia of direction.
