JEE MAIN - Physics (2023 - 12th April Morning Shift - No. 6)
Two satellites $$\mathrm{A}$$ and $$\mathrm{B}$$ move round the earth in the same orbit. The mass of $$\mathrm{A}$$ is twice the mass of $$\mathrm{B}$$. The quantity which is same for the two satellites will be
Potential energy
Kinetic energy
Total energy
Speed
Εξήγηση
The quantity which is same for the two satellites will be speed.
The orbital speed of a satellite is independent of the mass of the satellite, but it depends on the radius of the orbit. Potential energy, kinetic energy and total energy depend on the mass of the the satellite.
Therefore, the only quantity that is the same for the two satellites is speed.
