A cylinder of mass ' \( \mathrm{M} \) ' is suspended by two strings wrapped around it as shown. The acceleration ' \( a \) ' and the tension \( \mathrm{T} \) when the cylinder falls and the string unwinds itself is
(1) \( a=g, \mathrm{~T}=\frac{M g}{2} \)
(2) \( a=\frac{g}{2}, \mathrm{~T}=\frac{M g}{2} \)
(3) \( a=\frac{g}{3}, \mathrm{~T}=\frac{M g}{3} \)
(4) \( a=\frac{2 g}{\mathrm{~T}}=\frac{M g}{6} \)
