1.	Two particles of mass m each are rotating parallel to xz plane in circle of radius R as shown. They are connected by a mass less rod of length 2sqrt(2) R as shown. Consider the situation when the particles are at (R, R,0) and (-R, -R, 0). Neglect gravity and any kind of friction. Answer following questions Choose the correct statement
Answer» The y-component of the total torque ACTING on the system is non-zero Net force Solution :L in y direction remains constant `z_(y)=0` L at this instant is along x direction & rotates in xz PLANE `rArr Deltavec(L)` rotates in xz plane

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 ?
