Step 1: Understanding the Concept:
Geostationary satellites have specific orbital characteristics.
They are used for communication and weather monitoring.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand the properties of geostationary satellites.
Step 3: Detailed Explanation:
A geostationary satellite appears stationary from Earth.
It can continuously view the same area.
This is because it orbits at the same rate as Earth's rotation.
However, it orbits in the equatorial plane, not the polar plane.
It is at approximately 36,000 km above Earth.
Thus, Assertion A is correct.
Reason R is incorrect because it is not in the polar plane.
Step 4: Final Answer:
A is correct but R is not correct.
Hence, the correct option is (C).
