Question
Choose the correct statement from the following:
Assertion: The speed of a satellite always remains constant in orbit.
Reason: The speed of a satellite depends on its path.
- The assertion is correct, but the reason is wrong.
- Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
- Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
- The assertion is wrong, but the reason is correct.
Hint:
If the eccentricity of the orbit is 0, it is a circular orbit whereas if the eccentricity is 1, it is elliptical.
The correct answer is: The assertion is wrong, but the reason is correct.
Speed of satellite depends on distance between it's axis of rotation and itself. If the orbital path of a satellite is circular, then its speed is constant and if it is elliptical, then its speed in the orbit is not constant. In that case its areal velocity is constant.
Hence, both the assertion and reason are incorrect.
