1.	Figure shows a long cylindrical container with ideal gas in two chambers. Lower chamber is filled with one mole of a mono atomic gas, while upper chamber has one mole of a diatomic gas. The gases initially are at temperature 300K, the container walls as well as pistons are conducting. Both the pistons are identical with mass 'M' and area 'A' such that (Mg)/A=P_(0) (atmosphere pressure). Assuming the ideal gas constant to be R, answer the following questions: The upper piston is pulled up slowly by 16 cm and held there. the displacementof the lower piston till it reaches new equilibrium state is:
Answer» `2cm` `4CM` `8CM` `12cm` Solution :`P_("LOWER")-P_("upper")=P_(0)` `implies(3P_(0)xx(8))/((8+x))-(2P_(0)xx12)/((28-x))=P_(0)` `impliesx=4cm`

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 ?
