Assertion: In the sytem shown in figure ...

Assertion: In the sytem shown in figure spring is first stretched then left to oscillate. At some instant kinetic energy of mass `m` is K. At the same instant kinetic energy of mass `2m` should be `K/2`.

Reason: Their linear momenta are equal and opposite and `K=(p^2)/(2m)` or `K=1/m`.

A

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true, but the Reason is false.

D
