1.	In amplitude modulation, sinusoidal carrier frequency used is denoted by omega_( c) and the signal frequency is denoted by omega_(m). The bandwidth (Delta omega_(m)) of the signal is such that Delta omega_(m) lt lt omega_( c). Which of the following frequencies is not contained in the modulated wave?
Answer» `omega_(m)` `omega_(c )` `omega_(m) + omega_(c)` `OMEGA - omega_(m)` Solution :The RANGE of frequency of the modulated wave `= omega_(c) pm omega_(m)" " because" " omega_(c) gt gt Delta omega_(m)`, the frequency `omega_(m)` will not be contained in the modulated wave. `therefore ` The OPTION A is CORRECT.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
