Question

Assertion (A): The Moon revolves around the Earth.
[0.2cm] Reason (R): The Earth interacts with the Moon under its gravitational force.

Hint:

For assertion–reason questions: \begin{itemize} \item Check the truth of both statements separately, \item Verify whether the reason explains the assertion, \item Remember that gravitational force governs planetary motion. \end{itemize}

Answer 1

Step 1: The assertion is true because the Moon revolves around the Earth in a definite path.
Step 2: The reason is also true as the Earth exerts a gravitational force on the Moon.
Step 3: This gravitational interaction provides the necessary centripetal force for the Moon to move in an elliptical orbit around the Earth.
Step 4: Hence, the reason correctly explains the assertion.
