1.	The electric field vector of an electromagnetic wave is E=E_(0)sin [2pi ((x)/(lambda)-(t)/(T))]hat(j)a. Write the magnetic field vector of this wave.b.What is the direction of propagation ?c.With what velocity the wave propagates ?
Answer» Solution :a. `bar(B)=B_(0)sin[2pi((x)/(lambda)-(t)/(T))]hat(k)` b.X - DIRECTION (or along `hat(i)`) C. `c = upsilon lambda "" c=(1)/(SQRT(mu_(0)epsilon_(0)))` or `c=(1)/(sqrt(mu EPSILON))`(in a medium)

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 ?
