A mass 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?

A$\frac{3g}{3}$B$\frac{g}{2}$C$\frac{5g}{6}$Dg

Show answer and solution▾

[IMAGE] mg - T = ma....(1)
T.R = mR^2$\frac{a}{R}$....(2)
$\frac{g}{2} = a$
