Question

Not yet answered Points out of Flag question The electric field of an electromagnetic wave in vacuum is E rightarrow =(10 4 V/m) sin (10 6 rad/m) y-(3 times 1014 rad/s)t)i^ Which of these is a possible magnetic field of that wave? Select one: B rightarrow = (104 T) sin (106 rad/m)y-(3 times 1014 rad/s)i^ B rightarrow = (3.3 times 10-5 T) (10 6 rad/m)y-(3 times 10 14 rad/s)t) i^ B rightarrow = (3.3 times 10-5 T) sin (106 rad/m)y-(3 times 1014 rad/s) j^ B rightarrow = (104 T)sin (106 rad/m)y-(3 times 10 14 rad/s)k^ None of the above magnetic fields works. Answer saved Points out of Remove flag The diagram shows two unequal negative charges - q and - Q. Charge - Q has greater magnitude than charge - q. Point X is midway between the charges. In what section of the line will there be a point where the resultant electric field is zero? Select one: Nowhere XY WX YZ VW Not yet answered Points out of 1.00 Y Flag question A uniform, extensive sheet of charge carries a charge density of mu C/mm2.
