1.	In the figure shown 'PQRS' is a fixed resistanceless conducting frame is a uniform and constant magnetic field of strength B. A rod 'EF' of mass 'm' length 'l' and resistance R can smoothly move on this frame. A capacitor charged to a potential difference 'V_(0)' initially is connected as shown in the figure. Find the velocity of the rod as function of time 't' if it is released at t=0 from rest.
Answer» Answer :`V=(Blc " " V_(0))/(m+B^(2)L^(2)C)(1-e^(-((B^(2)l^(2))/(MR)+(1)/(RC))t))`

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 ?
