Question

Assertion: The telecommunication satellites are placed in geostationary orbit.
Reason: In a geostationary orbit, the relative distance of the satellite with respect to earth remains the same and hence it can cover a vast area for telecommunication.

• A. Both assertion and reason are correct statements and the reason is the correct explanation of the assertion.
• B. Both assertion and reason are correct statements but the reason is not the correct explanation of the assertion.
• C. The assertion is correct, but the reason is the incorrect statement.

Answer 1

The correct option is A

Both assertion and reason are correct statements and the reason is the correct explanation of the assertion.

The explanation for the assertion statement:

1. Geostationary orbit is a circular orbit at an altitude of 35,800km above the equator.
2. The satellite which is placed in geostationary orbit is called a geostationary satellite.
3. It revolves in the same direction as earth and takes 24 hours.
4. Satellites in geostationary orbit are used in telecommunication.
5. Therefore assertion statement is true.

The explanation for the reason statement:

1. The geostationary satellite revolves in the same direction as the earth therefore it appears stationary and covers a large area of the earth for telecommunication.
2. Therefore reason statement is true.

Concluding statement:

1. Both assertion and reason are correct statements and the reason is the correct explanation of the assertion.
2. Hence option A is the correct answer.
