Answer questionon the basis of yourunderstanding of the following paragraph and the related studied concepts. A Charges placed at a point in space produces an electric field everywhere in the surrounding. When another charge is borught in the field of first charge, it experiencesa force . The electric field at a point is space due to given charges is defind as the forcethat a unit positive charges would experience if placed at that point. It we consider a system of charges q_1, q-2,q_3 ..... with position vectors oversetto (r_1 ) , oversetto (r_2) , oversetto (r_3) ..... relative to some origin O, then electric field at a point in space due to the system of charges is determined by finding the vector sum of fields due to all individual charges of the charges system.

Answer» Solution :Evennow net field at O will be ZERO because even now electric fields DUE to diagonally OPPOSITE CHARGES are exactly equal in magnitude but opposite in direction and thus balance each other.

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 ?
