1.	Two blocks of mass m and 2m are kept in contact on a smooth horizontal surface. A horizontal pushing force F is applied on mass 2m in case I and on mass m in case II. Then the ratio of normal reaction between the blocks in case I to that in case II is :
Answer» `1 : `1 `1 : 2` `2 : 1` `1 : 3` Solution :In case I : `a_(1) = (F)/(3m) IMPLIES N_(1) = m a_(1) = (F)/(3)` In case II : `a_(2) = (F)/(3m) implies N_(2) = 2M a_(2) = (2F)/(3)``N_(1) : n_(2) = 1 : 1`

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 ?
