A hollow sphere of mass M and radius r is immersed in a tank of water (denstiy `rho_(w)`). The sphere would float if it were set free. The sphere is tied to the bottom of the tank by two wires which makes angle `45^(@)` with the horizontal as shown in the figure. The tension `T_(1)` in the wire is :

A uniform solid sphere of mass M and radius R is lying on a rough horizonal plane. A constant force F=4Mg acts vertically downwards at point P such that the line OP makes an angle of 60^(@) with the horizontal as shown in the figure. The minimum value of the coefficient of friction mu so that sphere performs pure rolling, is
