Question

Moon is revolving in a circular orbit around the earth with a uniform speed v. If the gravitational force suddenly disappears, then moon will

• A. Continue to move with velocity v along the original orbit
• B. fly away with a velocity v, tangentially to the original orbit
• C. Fall down with increasing velocity
• D. Ultimately come to rest somewhere on the original orbit

Answer 1

The correct option is B

fly away with a velocity v, tangentially to the original orbit

moon will fly away tangentially as there is no force to change its direction every moment.
