Given below are two statements: one is labelled as Assertion (A)...

For a coin placed on a rotating record player, the angular velocity $\omega$ is the same for all points.

The required centripetal force to prevent slipping is $F_c = m r \omega^2$. As the distance $r$ from the center increases (closer to the edge), the required centripetal force increases. Since the maximum static friction $f_s = \mu m g$ is constant, the coin is more likely to slip at a larger radius. Thus, the Assertion is true.

The Reason states that for a constant radius, $F_c \propto \omega^2$. This is a true statement based on $F_c = m r \omega^2$. However, it does not explain the Assertion, which is based on the variation of $F_c$ with radius $r$ at a constant $\omega$.

Therefore, both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.

Answer: Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
