A right angled prism is immersed in water. Whena ray of light is incident normally on a side adjacent to the right angle, the ray is totally reflected from the face opposite to the right angle and emerges through the other adjacent side of the right angle. But if the ray is incident normally on the face opposite to the right angle and no internal reflection takes place. If the other two angles of the prism are 60^(@) and 30^(@) respectively what is the range of the value of the refractive index of the material of the prism?

1.	A right angled prism is immersed in water. Whena ray of light is incident normally on a side adjacent to the right angle, the ray is totally reflected from the face opposite to the right angle and emerges through the other adjacent side of the right angle. But if the ray is incident normally on the face opposite to the right angle and no internal reflection takes place. If the other two angles of the prism are 60^(@) and 30^(@) respectively what is the range of the value of the refractive index of the material of the prism? Refractive index of water in vacuum = 1.33

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 ?
