365715 A pulley fixed to the ceiling carries a string with blocks of mass \(m\) and \(3\;\,m\) attached to its ends. The masses of string and pulley are negligible. When the system is released,its center of mass moves with acceleration of

1 \(g / 4\)
2 0
3 \(g / 6\)
4 \(g / 2\)
PHXI07:SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

365716 Both the blocks shown in the given arrangement are given together a horizontal velocity towards right. If \({x {~ms}^{-2}}\) be the subsequent acceleration of centre of mass of the system of blocks, find the minimum value of \({x}\)
(Given, \({m_{A}=2 m_{B}}\) and \({g=10 {~ms}^{-2}}\), all in SI units)
