Question

If height of a satellite from the surface of earth is increased, then its (A) Potential energy will increase (B) Kinetic energy will decrease (C) Total energy will increase (D) All of these

Tardigrade Admin · Accepted Answer

For a satellite orbiting at height h from earth, P.E =-(G Me ms/(Re+h)) K.E =(G Me ms/2(Re+h)) T.E =-(G Me ms/2(Re+h)) If h is increased, P.E increases (becomes less negative) K.E decreases T.E increases (becomes less negative)

Q. If height of a satellite from the surface of earth is increased, then its

Potential energy will increase

Kinetic energy will decrease

Total energy will increase

All of these

For a satellite orbiting at height h from earth, P.E=−(Re​+h)GMe​ms​​ K.E=2(Re​+h)GMe​ms​​ T.E=−2(Re​+h)GMe​ms​​ If h is increased, P.E increases (becomes less negative) K.E decreases T.E increases (becomes less negative)
