A string is wrapped around a cylinder of mass \( M \) and radius \( R \). The string is pulled vertically upwards to prevent the
\( \mathrm{P} \) centre of mass from falling as the cylinder unwinds the

W string. The tension in the string is
(1) \( \frac{M g}{6} \)
(2) \( \frac{M g}{3} \)
(3) \( \frac{M g}{2} \)
(4) \( \frac{2 M g}{3} \)
