Question

Assertion: Sun-synchronous satellites pass over a particular place on the earth in a fixed daytime.
Reason: Sun-synchronous satellites are used for spying purposes.

• 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.
• D. The assertion is incorrect but the reason is the correct statement.

Answer 1

The correct option is B

Both assertion and reason are correct statements but the reason is not the correct explanation of the assertion.

The explanation for the assertion statement:

1. Sun-synchronous satellite: The satellite that is placed in a sun-synchronous orbit (SSO).
2. It is a polar orbit around earth.
3. It is synchronous to the sun which means that it is at a fixed position with respect to the sun.
4. It means the satellite always passes over a particular area on the earth at approximately the same local time.
5. This arrangement enables the satellite to take pictures with almost the same intensity of light.

The explanation for the reason statement:

1. Since the sun-synchronous satellite is placed at a fixed position it means it takes pictures with the same intensity of light therefore it is used for spying purposes.

Concluding statement:

Hence the correct answer is option B.
