1.	An electric charge 10^(-3)mu C is placed at the origin (0,0) of x-y coordinate system. Two points A and B are situated at (sqrt2, sqrt2) and (2,0) respectively. The potential difference between the points A and B will be
Answer» zero 9V 4.5 V 2V Solution : Here distance of point `A [ sqrt 2, sqrt 2]`from charge point `[0,0] = 2` and distanceof point B[2,0] from charge point [0,0] is ALSO 2. `:. V_A = V_B = q/(4 PI epsi_0.r)` and hence `V_A - V_B = 0`

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 ?
