A horizontal weightless rod of length 3l is suspended on two vertical strings. Two loads of mass m_(1) and m_(2) are in equilibrium at equal distance from each other and from the ends of the strings (Fig). Determie the tension T of the left string at the instant when the right string snaps.

Three girls skatting on a circular ice ground of radius 200 m start from a point P on the edge of the ground and reach a point Q diametrically opposite to P following different paths as shown in Fig . 4.20 . What is the magnitude of the displacement vector for each ? for which girl is this equal to the actual length of path skate ?
