Two satellites \(A\) and \(B\) move round the earth in the same orbit. The mass of \(A\) is twice the mass of \(B\). The quantity which is same for the two satellites will be :
- A Potential energy
- B Total energy
- C Kinetic energy
- D Speed
Answer & Solution
Correct Answer
(D) Speed
Step-by-step Solution
Detailed explanation
P.E \(=-\frac{G M M_p M_A}{R}\) \(K.E=+\frac{G M_p M_A}{2 R}\) \(T.E =-\frac{ GM _{ p } M _{ A }}{2 R }\) Speed \(=v=\sqrt{\frac{G M_p}{R}}\) Speed of satellite in Independent of mass of satellite.
