1.	An electron (mass = 9.0xx10^(-31)kg and charge = 1.6xx10^(-19)coulomb) is moving in a circular orbit in a magnetic field of 1.0xx10^(-4)Wb//m^(2). Its period of revolution is _______ .
Answer» `3.5xx10^(-7)s` `7.0xx10^(-7)s` `1.05xx10^(-6)s` `2.1xx10^(-6)s` SOLUTION :`m=9xx10^(-31)kg` `B=1xx10^(-4)Wb` `q=1.6xx10^(-19)C` The periodic time of the MOTION of ELECTRON, `T=(2pim)/(qB)` `thereforeT=(2xx3.14xx9xx10^(-31))/(10^(-4)xx1.6xx10^(-19))=3.5xx10^(-7)s`

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 ?
