Figure shows a string stretched by a block going over a pulley. The string vibrates in its tenth harmonic in unison with a particular tuning fork. When a beaker containing water is brought under the block so that the block is completely dipped into the beaker, the string vibrates in its eleventh harmonic. Find the density of the material of the block.

A string is stretched by a block going over a pulley . The string vibrates in its fifth harmonic in unison with a particular tuning fork . When a beaker containing a liquid of density rho is brought under the block so that the block is completely dipped into the beaker , the string vibrates in its seventh harmonic in unison with the tuning fork . Find the density of the material of the block.

Figure shows a string stretched by a block going over a pulley. The string vibrates in its tenth harmonic in resonance with a particular tuning fork. When a beaker containing water is brought under the block so that the block is d "gram"//"cm"^(3) then find greatest integer of d . (node is formed at the pulley)

When block hangs in air, the horizontal string vibrates in its tenth harmonic in unison with a particular tuning fork. When block is placed in elevator acceleration in downward direction, the same string vibrates in its eleventh harmonic with same tuning fork. What will be acceleration of elevator ?

The string AB vibrates in two loops with a tuning fork when block hasngs in air. Now block is completely immersed in water, the string vibrates in three loops with same tuning fork. The specific gravity of block is :

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 ?
