Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A :\) Earth has atmosphere whereas moon doesn't have any atmosphere. Reason \(R\) : The escape velocity on moon is very small as compared to that on earth. In the light of the above statement, choose the correct answer from the options given below :

Pick an option to check your answer.

Verified Solution

Answer & Solution

Correct Answer

(D) Both \(A\) and \(R\) are correct and \(R\) is correct explanation of \(A\)

Step-by-step Solution

Detailed explanation

At Moon, due to low escape velocity, the rms velocity of molecules is greater than escape velocity. Hence molecules escape and there is no atmosphere at Moon.
