$$1$$. GivenWave Frequency  $$=25$$ MHzIntensity of Electric Field E¯$$=6.3j^$$ $$V/mThe$$ magnitude of the magnetic field is given $$byB=Ec=6.33$$×$$108=2.1$$×$$10$$−$$8$$ T. $$2$$. The vector  E→×B→ should be along  $$x-direction$$, and $$soj^$$×$$A^=i^$$,  indicates that  $$A^=k^$$.Thus,  B→$$=2.1$$×$$10$$−$$8k^$$ T.Therefore, the correct answer is (C).

A plane electromagnetic wave of frequency 25MHz travels in free space along the x-direction . At a particular point in the space and time, if the intensity of electric field $\vec{E} = 6.3 \hat{j} V / m$ , the magnetic induction $\vec{B}$ at this point is
