3. Two conducting rings P and Q of radii r and 2r moving uniformly in opposite directions with
centre of mass velocities 2v and v respectively on a conducting surface S. There is a uniform field of magnitude B perpendicular to the plane of the rings.
The potential difference between the highest points of the two rings is

In an electromagnetic wave, the magnetic field is given by
$B_y=2*10^{-7}sin(0.5*10^3x+1.5*10^{11}t)T.$
The intensity of e.m. wave is about
