When a particle is restricted to move along x-axis between x=0 and x=a , where alpha if of nenometer dimension, its energy can take only certain specific values. The allowed energies of the particle moving in such a restricted region, correspond to the formation of standing waves with nodes at its ends x=0 and x=a . The wavelength of this standing wave is related to the linear momentum p of the particle according to the de Broglie relation. The energy of the particle of mass m is related to its linear momentum as E=(p^2)/(2m) . Thus the energy of the particle can be denoted by a quantum number n taking values 1,2,3, ...( n=1 , called the ground state) corresponding to the number of loops in the standing wave. Use the model described above to answer the following three questions for a particle moving along the line from x=0 to x=alpha . Take h=6.6xx10^(-34)Js and e=1.6xx10^(-19) C Q. The speed of the particle that can take discrete values is proportional to

A chain (AB) of length l loaded in a smooth horizontal table so that its fraction of length h hangs freely and toucher the surface of the table with its end B. At a certain moment ,the end A of the chain is set free. With what velocity will this end the chain slip out of the table ? .

A wheel of rdius r and moment of inertia I about its axis is fixed at top of an inclined plane of inclination theta as shownin figure. A string is wrapped round the wheel and its free end supports a block of mass M which can slide on the plane. INitialy, tehwheel is rotating at a speed omega in direction such that the block slides pu the plane. How far wil the block move before stopping?

A particle of mass m is attached to one end of a weightless and inextensible string of length L. The particle is on a smooth horizontal table. The string passes through a hole in the table and to its other and is attached a small particle of equal mass m. The system is set in motion with the first particle describing a circle on the table with constant angular velocity omega_(1) and the second particle moving in the horizontal circle as a conical pendulum with constant angular velocity omega_(2) Show that the length of the portions of the string on either side of the hole are in the ratio omega_(2)^(2): omega_(1)^(2)
