PassageII We have two parallel plate capacitors P and Q having same capacitance C_(0). P is connected to a battery of potential difference V and it remains connected to the battery even after the charging is over. Q is also connected to a battery of the same potential difference V but after the charging gets over, it is disconnected from the battery. Answer the following questions: If a dielectric slab of dielectric constant 5 is inserted in between the plates of P so that the entire space is occupied by the dielectric and if U is the energy stored before the insertion of dielectric then stored energyafter the dielectric slab is introduced is

1.	PassageII We have two parallel plate capacitors P and Q having same capacitance C_(0). P is connected to a battery of potential difference V and it remains connected to the battery even after the charging is over. Q is also connected to a battery of the same potential difference V but after the charging gets over, it is disconnected from the battery. Answer the following questions: If a dielectric slab of dielectric constant 5 is inserted in between the plates of P so that the entire space is occupied by the dielectric and if U is the energy stored before the insertion of dielectric then stored energyafter the dielectric slab is introduced is
Answer» U `U//5` 5U None of these SOLUTION :In the given passage we should KNOWN that potential difference between the plates of P remains constant whereas charge stored in Q will REMAIN constant. All ANSWER are to be obtained keeping these things in mind.

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 ?
