A smooth pulley `P_0` of mass `2 kg` is lying on a smooth table. A light string passes round the pulley and has masses `1 kg` and `3 kg` attached to its ends. The two portions of the string being perpendicular to the edge of the table so that the masses hang vertically. Pulleys `P_1` and `P_2` are of negligible mass. [ `g=10m//s^2`]

Acceleration of pulley `P_0` is

Options

A. `2m//s^2`
B. `4m//s^2`
C. `3m//s^2`
D. `6m//s^2`

Answer

D
