1.	Which of the following statements (s) is//are correct ?
Answer» If the electric field due to a point charge varies as `r^(-2.5)` instead of `r^(-2)`, then Gauss's law will still be valid. Gauss's law can be used to CALCULATE the field distribution around an electric dipole. If the electric field between two point charges is zero somewhere, then the sign of the two charges is the same. The WORK done by the external force is moving a unit positive charge from point A at POTENTIAL `V_A` to point B at potential `V_B is (V_B - V_A)` . Solution :a. This option is wrong, because flux due a charge through a gaussian surface (in which the charge is present) will DEPEND upon the shape and size of the surface. b. it is almost impossible to calculate the field distribution around an electric dipole using gauss's law because proper symmetry will not be formed c. This is obvious d. This options is not correct because it is not given that charge is moving slowly.

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 ?
