1.	Fig (a) and (b) show the field lines of a single positive and negative charges respectively . Give the sign of the potential energy difference of a small negative charge between the points Q and P , A and B .
Answer» Solution :POTENTIAL energy difference of a SMALL NEGATIVE CHARGE -q between the points Q and P will be -q `(V_(Q) - V_(P)) = q (V_(P) - V_(Q))` and it will be +ve . Again potential energy difference of this negative charge between the points A and B will be -q `(V_(A) - V_(B)) = q (V_(B) - V_(A))` and it will also be +ve .

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 ?
