Q. A satellite revolving around the Earth loses some energy due to collision. What would be the effect on its velocity and distance from the centre of the Earth ?

Gravitation Report Error

Velocity increases and distance decreases

Both velocity and distance increase

Both velocity and distance decrease

Velocity decreases and distance increases

Solution:

As it looses some energy, it will be attracted toward the earth and distance decreases and due to work done by gravity its interaction energy decreases and kinetic energy increases hence option (A) is correct.
