1.	(a) When an unpolarised light of intensity I_(0) is passed through a polaroid, what is the intensity of the linearly polarised light ? Does it depend on the orientation of the polaroid ? Explain your answer. (b) A plane polarised beam of light is passed through a polaroid. show graphically the variation of the intensity of the transmitted light with angle of rotation of the polaroid in complete one rotation.
Answer» Solution :(a) When an UNPOLARISED LIGHT of INTENSITY `I_(0)` is passed through a polaroid, the intensity of linearly polarised light obtained on other side of polaroid is `I=I_(0)//2`. It does not DEPEND on the orientation of the polaroid. If the polaroid is rotated, the direction of orientation of electric vector of transmitted light changes but intensity of light remains UNCHANGED.

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 ?
