1.	A ray of light ab passing through air enters a liquid of refractive index mu_(1) at the boundary XY. In the liquid, the ray is shown as bc. The angle between ab and bc ( angle of deviation) is delta. The ray then passes through a rectangular salb ABCD of refractive index mu_(2)(mu_(2)gtmu_(1)) and emerges from the slab as the ray de. The angle between XY and AB is theta. The angle between ab and de is
Answer» `DELTA` `delta+theta` `delta+sin^(-1)((mu_(1))/(mu_(2)))` `delta+theta-sin^(-1)((mu_(1))/(mu_(2)))` ANSWER :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 ?
