A mass \( m \) is supported by a massless string wound around a uniform hollow cylinder of mass \( m \) and radius \( R \). If the string does not slip on the cylinder, with what acceleration will the mass fall on release?
(1) \( \frac{5 g}{6} \)
(2) \( g \)
(3) \( \frac{2 g}{3} \)
(4) \( \frac{g}{2} \)
