1.	The efficiency of Carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2). The eficiency of another Carnot's heat engine is also 0.5. The temperatures of source and sink of the second engine are respectively
Answer» `2T_(1),2T_(2)` `2T_(1),(T_(2))/(2)` `T_(1)+5,T_(2)-5` `T_(1)+10, T_(2)-10` SOLUTION :Efficiency of Carnot.s heat ENGINE, `eta=1-(T_(2))/(T_(1))` Efficiency remains same when both `T_(1) and T_(2)` are INCREASED by same factor. So, correct choice is (a).

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 ?
