1.	A source of sound emitting a frequency 660 Hz is moving counter-clockwise in a circular path of radius 2 metres with an angular velocity 15 rad/s. A recorder at a distance from the source is moving simple harmonically along a straight line with an amplitude 2 metres. The frequency of SHM is 15/(2pi)per second. The arrangement is shown in figure. When the source is at point A the detector is at D. Find the maxium and minimum frequencies recorded. Velocity of sound in air at this temperature can be taken as 300 m/s
Answer» 870 HZ, 480 Hz 733.4 Hz, 600 Hz 680 Hz, 380 Hz 580 Hz, 280 Hz Answer :B

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 ?
