Question

Given below are two statements Statement-I: Geostationary satellite orbits the Earth at an altitude of 700- 900 km. Statement-II: Geostationary satellites are used to monitor the weather and telecommunication. The correct answer is

• A. Only statement-I is correct
• B. Only statement-II is correct
• C. Both statement-I and statement-II are correct
• D. Both statement-I and statement-II are incorrect

Hint:

A geostationary satellite orbits in the equatorial plane with a period equal to one day, so it appears fixed over a point on Earth. This requires a very specific, high altitude.

Answer 1

The Correct Option is B

Step 1: Recall what geostationary means.
A geostationary satellite goes around the Earth once per day above the equator, so it seems to stay fixed over one spot on the ground.

Step 2: Check Statement-I about altitude.
To match Earth's spin, the satellite must sit very high, at about 36000 km. The figure of 700 to 900 km is wrong; that low range belongs to sun synchronous satellites.

Step 3: Decide on Statement-I.
Since the altitude given is far too low, Statement-I is incorrect.

Step 4: Check Statement-II about uses.
Because a geostationary satellite stares at the same region all the time, it is ideal for weather watching and telecommunication.

Step 5: Decide on Statement-II.
So Statement-II is correct.

Step 6: State the answer.
Only Statement-II is correct.
\[ \boxed{\text{Only statement-II is correct}} \]
