Assertion: The centre of mass of system of \( n \) particles is the weighted average of the position vector of the \( n \) particles making up the system.
Reason: The position of the centre of mass of a system is independent of coordinate system.
(1) Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
(2) Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
(3) Assertion is correct but Reason is incorrect
(4) Assertion is incorrect but Reason is correct
