Questions
A satellite is moving in a circular orbit around the earth with kinetic energy K. Due to collision with dust particles, it slowly loses 50% of its energy and finally starts rotating in a circular orbit of smaller radius. Then the kinetic energy of the satellite in this new orbit is
detailed solution
Correct option is D
Initial total energy = -KFinal total energy =(−K)−K2=−3K2∴ Final kinetic energy =+3K2Talk to our academic expert!
