Pulley is rotating with angular velocity $ω$ . Pulley is sufficiently rough so that string does not slip on the pulley. Then angular momentum of system (pulley + blocks) about axle of pulley is :-

Options:

Answer:

Solution:

String does not slip, so each block moves with speed $v = r ω$

Angular momentum of the system about the axle:

$L = m_{1} v r + m_{2} v r + I ω$

$L = (m_{1} + m_{2}) r^{2} ω + I ω$
