Q- A pulley wheel of radius r and mass m is free to rotate about a fixed smooth horizontal axis through its center perpendicular to the plane of the pulley? A light in-extensible string passes over the pulley and carries particles of mass 4m and 2m, one at each end of the string. It can be assumed that the pulley wheel can be modeled as a uniform circular disc and that the string does not slip on the pulley. Find the tension in each vertical part of the string.
