1.	A laser beam and a sound wave from directional sources both enter a liquid at an angle of 60^(@) from the horizontal surface of the liquid. The speed of sound in the liquid is 5 times than that of the speed of the sound in air. For light, the refractive index of the liquid is 1.8. What happens ?
Answer» Both the light and the SOUND REFRACT at an angle of `74^(@)` from the horizontal The light refracts to an angle of `26^(@)` from the horizontal and the sound refracts to an angle of `74^(@)` from the horizontal The light refracts to an angle of `26^(@)` from the horizontal and the sound reflection COMPLETELY off the surface. The light refracts to an angle of `74^(@)` from the horizontal and the sound refracts to an angle of `26^(@)` FORM the horizontal 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 ?
