The momentum density of an electromagnetic wave is defined as Doro(EXB). The direction of the momentum density denotes the direction of the propagation of an electromagnetic wave. At a particular instant, the electric field associated with an electromagnetic wave propagating in free space is directed along the positive x-axis and the magnetic field is along the positive z-axis, as shown in the figure. z B E What is the direction of propagation for this electromagnetic wave? The electromagnetic wave propagates:...

A proton and an electron have charges e and –e. They are moving
with the same speed in opposite directions, as you can see above.
At a particular moment, the proton is at a distance d directly
above the electron. At this moment, the velocity of the electron
points in the positive x-axis and the velocity of the proton points
in the negative x-axis.
A. What is the direction of the magnetic field from the electron
at the location of...
