1.	A parallel plate capacitor of plate are A and plate seperation d is charged to potential difference V then the battery is disonnected . A slab of dielectric K is then inserted between the plates of the capacitor so as to fill the space between the plates . If Q , E and W denote respectively. the magnitude of charge on each plate. the electric field between the plates (after the slab in inserted and the work done on the system , in question , in the process of inserting the slab, then )
Answer» `Q=(epsilon_0AV)/d` `Q=(epsilon_0KAV)/d` `E=(V//K)/d` `W=(epsilon_0AV^(2))/("2 d") (1-1/K)` Answer :A::C::D

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 ?
