Question

If the orbital velocity of moon is increased by 41.4% of its present value, then the-

• A. moon will orbit around earth with double velocity
• B. radius of moon's orbit will become double
• C. moon will become stationary satellite
• D. moon will leave its orbit and escape into space

Answer 1

The correct option is D moon will leave its orbit and escape into space

If the orbital velocity of the moon increased of its present value then it will escape from Earth's gravity causing it to float into the vastness of the universe. The gravitational force exerted by earth on the moon keep sit on the orbit and if the velocity increases then the Earth would no longer be able to hold the moon.
