Question

Assertion :Two satellites A and B are in the same orbit around the earth, B being behind A. B cannot overtake A by increasing its speed. Reason: It will then into a different orbit.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

We know that,

Orbital speed = $v_o\alpha \sqrt{\frac{GM}{R}}$

Since, $v_o$ is inversely proportional to $R$ , hence when B increases its speed it will go into different orbit.
