Question

What acceleration will the mass fall on release? 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.
A. 5g/6
B. 2g/3
C. G/2
D. G

Answer 1

For the mass m,
mg - T = ma
For the cylinder,
TR = mR2 a/R
T = ma
mg = 2ma
a = g/2
The correct option is C.
