Answer» perpendicular to the field parallel to the field with different speeds from opposite directions Solution :Electric field will APPLY force on charges in its direction only as the charges are positive EVEN if we PROJECT them from opposite directions. If we project the particles from opposite directions in the magnetic field, then the direction of the masnetic force will be opposite for both the particles. It means that on firing particles from opposite directions, if they deviate in the same direction, then the field MUST be electric and if they are found to deviate opposite, then it must be the magnetic field. Hence, option (d) is 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 ?
