The magnetic field in the plane electromagnetic wave is given by
`B_(z)=2xx10^(-7) sin(0.5xx10^(3)x+1.5xx10^(11)t)` tesla.
The expression for electric field will be:

A

`vecE=-60sin(0.5xx10^3x+1.5xx10^(10)t)hatjVm^(-1)`

B

`vecE=+60sin(0.5xx10^3x+1.5xx10^(10)t)hatjVm^(-1)`

C

`vecE=+60sin(0.5xx10^(11)x+1.5xx10^(3)t)hatjVm^(-1)`

D

`vecE=-60sin(0.5xx10^3x+1.5xx10^(11)t)hatjVm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=B_(0)c`
`=2xx10^(-7)xx3xx10^(8)`
`10V//m`
`therefore vecE=-60sin(0.5xx10^(3)x+1.5xx10^(11))hatj" "V//m`.
