One end of a horizontal string is attached to a vibrating blade , and the other end passes over a pulley as in Fig. 7.49 (a). A sphere of mass 2.00 kg hangs at the end of the string . The string is vibrating in its second harmonic . A container of water is raised under the sphere so that the sphere is completely submerged . In this configuration , the string vibrates in its fifth harmonic as shown in Fig . 7.49 (b). What is the radius of the sphere ?

Consider the situation shwon in Fig. 7.49 . The horizontal surface below the bigger block is smooth . The coefficient of friction between the blocks is mu . Find the minimum and maximum accelerations with which the system should move in order to keep the smaller blocks at rest with respect to the bigger block .

Refer to Fig. 7.49 . Now the switch is opened after closing it for a long time. Find the total energy dissipated in the system.

Refer to Fig. 7.49 . Long time after closing the switch , find the current through the 5 Omega resistor.
