Paragraph for Questions 11 and 12
iz'u 11 ,oa 12 ds fy;s vuqPNsnIn presence of the field the charge carriers in a solid behave as if they had an effective mass m* differentfrom the mass m of a charge carriers in absence of any field. The knowledge of value of m* is veryimportant for the understanding of the detailed theory of conduction in solid. The same can beexperimentally obtained by using a cyclotron in which apart from magnetic field some external electricfield is also applied which is varied till resonance is obtained. This is called cyclotron resonance.Cyclotron resonance describes the interaction of external forces with charged particles experiencing amagnetic field thus already moving on a circular path.Consider the case shown below :
w
B
E
Assuming mean free path l ® ¥ for the electron, they move in helical orbits as shown under the influenceof magnetic field. An electric field of constant magnitude, whose direction rotates with angular frequencyw, is also imposed on the solid in the plane shown.In the experiment w is fixed and the value of B is adjusted until the amount of input energy requiredto keep the amplitude of electric field constant reaches maximum.fdlh Bksl esa {ks= yxkus ij mlesa fo|eku vkos'k okgd bl izdkj O;ogkj djrs gSa tSls fd mudk izHkkoh æO;eku m*

A slip of paper is given to A. who marks it with either a plus sign or a minus sign, the probability
of his writing a plus sign is known to be 1
3. He then passes the slip to B, who may either leave it
alone or change the sign before passing it on to C. Next C passes the slip to D after perhaps changing
the sign. Finally D passes it to an honest judge after perhaps, changing the sign. It is known that B,
C and D each change the sign with probability 2/3.
