1.	Consider a thin conducting shell of radius R carrying total charge Q. Two point charges Q and 2Q are placed on points A and B, which are at a distances of R/2 and 2R from the center of the cell respectively as shown in the figure. If the cell is earthed how much charge will flow to the eart?
Answer» `3Q` `Q` `2Q` `Q/2` Solution :Since SHELL is earthed its potential is ZERO `(KQ^(1))/R+(K(2Q))/(2R)=0` `:. Q^(1)=-Q` Hence `3Q` will flow to the earth

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 ?
