1.	Consider a source of sound S and an observer P. The sound source is of frequency n_0. The frequency observed by P is found to be n_(1)if P approaches S at speed v and S is stationary, n_2 if S approaches P at a speed v and P is stationary and n_3 if each of P and S has speed v/2 towards one another. Now,
Answer» `n_(1) = n_(2) =n_(3)` `n_(1) lt n_(2)` `n_(3) GT n_(0)` `n_(3)` lies between `n_(1)` and `n_(2)` ANSWER :B::C::D

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 ?
