1.	A parallel-plate capacitor is clamped to a stand such that its plates are vertical. It remains connected to a cell through a centre-zero galvanometer. A metal sheet which is parallel to the plate of the capacitor and whose thickness is slightly less than the seperation between these plates is now allowed to fall under gravity though the plates, wihtout touching them. Which of the following correctly describes the deflection(s) of the galvanometer?
Answer» It will SHOW a constant deflection to ONE side only, as long as the sheet is PASSING through the plates. It will show a variable deflection to one side only, as long as the sheet is passing through the plates. It will show deflection FIRST to one side and then to the other. It will not show any deflection first to one side and then to the other. Answer :C

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 ?
