1.	There is a fixed positive charges Q at O, and A and B are points equidistant from O. A positive charge +q is taken slowly by an external agent from A to B along the line AC and then along the line CB.
Answer» The TOTAL work done on the charge is zero. The work done by the electrostatic force from A to C is negative. The work done by the electrostatic force from C to B is positive. The work done by electrostatic force in taking the charge from A to B is dependent on the actual path. SOLUTION :a.,b.,c. (a) is correc because potential of `A` and `B` is same. (b) is correct because charge is going from LOW potential to high potential. Electric potential energy increases and electrostatic forces do negative work. Similarly (c) is ALSO correct.

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 ?
