One long conductor carries current I along y-axis with charge density

1.	One long conductor carries current I along y-axis with charge density lambda. An electric field exists along z-axis. In what direction, a charged particle at point P, distance x apart from the wire (along x-axis), be projected with velocity v so that it moves undeflected?
Answer» VERTICALLY upward vertically downwards HORIZONTALLY RIGHT horizontally left Solution :If the particle is projceted vertically upwards, the TWO FORCES may be equal and the particle may move undeviated. .

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 ?
