A plane electromagnetic wave travels in free space along 2-axis. At a particular point in space, the electric field along y-axis is 9.3 V m^(-1). The magnetic induction (B) along z-axis is

Answer»

`3.1 xx 10^(-8) T`
`3 xx 10^(-5) T`
`3 xx 10^(-6) T`
`9.3 xx 10^(-6) T`

Solution :VELOCITY of light
`C=(E)/(B) IMPLIES B=(E)/(C)=(9.3)/(3 xx 10^(8))=3.1 xx 10^(-8) T`
