An artificial satellite with a metal surface is moving about the earth in a circular orbit. A current will be induced in the satellite, if

Options

  1. Athe plane of the orbit coincides with the plane of the equator.
  2. Bthe plane of the orbit is inclined to the plane of the equator.
  3. Cthe plane of the orbit coincides with the plane of the equator and the speed of the satellite is more than 8 &
  4. Dthe plane of the orbit coincides with the plane of the equator and the speed of the satellite is less than 8 &

Correct answer

B. the plane of the orbit is inclined to the plane of the equator.

Step-by-step solution

According to Faraday's law of electromagnetic induction, EMF will be generated across the ends of the conductor when the magnetic flux through a loop of the conductor will change with respect to time. When the orbit of the satellite is inclined to the equator of the earth, the distance from poles and hence magnitude of the magnetic field due to earth will change at different positions of orbit. This causes a change in magnetic flux across the metal plate of the satellite and EMF will be generated.
