1.	The electricfield E due to a point charge at any point near it is defined as "" E= underset( q_0to 0) lim (F)/(q_0)Draw the electric field lines of a point chargeQ when (i)Q gt 0, and (ii)Q lt 0.
Answer» SOLUTION :In the definition of ELECTRIC field E we TAKE test CHARGE `q_0` as small as possible so that presence of test charge does not AFFECT the electric field at all. That.s why we consider ` undersetto (qto 0) lim ` Electric field lines of a point charge (i) ` Q gt 0, and (ii) Q lt 0 ` have been plotted in respectively.

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 ?
