1.	A parallel plate air capacitor is connected to a battery. The quantities charge, voltage, electric field and energy associated with this capacitor are given by Q_(0),V_(0),E_(0) and U_(0) respectively. A dielectric slab is now introduced to fill the space between the plates with the battery still in connection. The corresponding quantities now given by Q,V,E
Answer» `QgtQ_(0)` `VgtV_(0)` `EgtE_(0)` `UgtU_(0)` Solution :When electric stab is introduced capacity GETS increased while potential DIFFERENCE remains unchanged `V=V_0,CgtC_0 ,Q=CV therefore QgtQ_0` `U=1/2CV^(2) therefore ugtU_0,E=v/d` but v and d both are unchanged . Therefore ,`E=E_0`, Therefore correct OPTION are (A) and (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 ?
