1.	In the Fig. two neutral spherical conductors of radii 2a and a are separated by a large distance. Initially, switch S_(1) is kept closed and S_(2) is open. Now S_(1) is opened and S_(2) is closed at t = 0. (a) Find the rate of fall in potential of the conductor of radius 2a as a function of time. (b) find the heat dissipated after S_(2) is closed.
Answer» ANSWER :(a) `(V)/((8pi in_(0)a)R)E^((-3t)/(8 pi in_(0)aR))` (b) `(4PI in_(0)aV^(2))/(3)`

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 ?
