We have two radioactive nuclei A and B. Both convert into a stable nucleus C. Nucleus A converts into C after emitting two alpha -particles and three beta -particles. Nucleus B converts into C after emitting one alpha -particle and five beta -particles. A time t = 0, nuclei of A are 4N_0 , and that of B are N_0 . Half-life of A into the conversion of C) is 1min and that of B is . 2 min. Initially number of nuclei of C are zero (a) If mass numbers of A and B are A_1 and A_2respectively. Then find A_1 -A_2 (b) What are number of nuclei of C, when number of nuclei of A and B are equal (c) At what time rate of disintegrations of A and B are equal

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 ?
