1.	The direction of ray of light incident on a concave mirror is shown by PQ while directions in which the ray would travel after reflection is shown by four rays marked 1, 2, 3 and 4 (See figure). Which of the four rays correctly shows the direction of reflected ray ?
Answer» 1 2 3 4 Solution :Here ray `vec(PQ)`, is PASSING through principle FOCUS F while being INCIDENT on a concave mirror. Hence after getting reflected, it should be rendered parallel to principal AXIS of the mirror. Thus, path no. 2 is correct path for ray `vec(PQ)`.

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 ?
