371872 The maximum and minimum tensions in a string whirling in a circle of radius \(2.5 \mathrm{~m}\) are in the ratio \(5: 3\). Then, its velocity is m.s :

371873 Two bodies of mass \(4 \mathrm{~kg}\) and \(6 \mathrm{~kg}\) are tied to the ends of a massless string. The string passes over a pulley which is frictionless (see figure). The acceleration of the system in terms of acceleration due to gravity \(g\) is

371874 A body of mass \(2 \mathrm{~kg}\) is acted upon by two each of magnitude \(1 \mathrm{~N}\) and inclined at \(60^{\circ}\) with each other. The acceleration of the body in \(\mathrm{m} / \mathrm{s}^{2}\) is \(\left(\cos 60^{\circ}=0.5\right)\)

371875 A see-saw of length \(6 \mathrm{~m}\) is pivoted at its centre. A child of mass \(20 \mathrm{~kg}\) is sitting at one of its ends. Where should another child, of mass 30 \(\mathrm{kg}\), sit on the other end from the centre of seesaw, so that it is balanced ?
