प्रश्न

Two satellites A and B move round the earth in the same orbit. The mass of B is twice the mass of A.

विकल्प

  • Speeds of A and B are equal.

  • The potential energy of earth+A is same as that of earth+B.

  • The kinetic energy of A and B are equal.

  • The total energy of earth+A is same as that of earth+B.

उत्तर

Speeds of A and B are equal.

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.
