Two identical uniform discs of mass \( m \) and radius \( r \) are arranged as shown in the figure. If \( \alpha \) is the angular acceleration of
\( \mathrm{P} \) the lower disc and \( a_{\mathrm{cm}} \) is acceleration of

W centre of mass of the lower disc, then relation among \( a_{\mathrm{cm}}, \alpha \) and \( r \) is
(1) \( a_{\mathrm{cm}}=\frac{\alpha}{r} \)
(2) \( a_{\mathrm{cm}}=2 \alpha r \)
(3) \( a_{\mathrm{cm}}=\alpha r \)
(4) none of these
