In an apparatus the electric field was found to oscillate with an amplitude of `18` `V//m`. The magnitude of the oscillating magnrtic field will be

Options

A. `4xx10^(-6) T`
B. `6xx10^(-8) T`
C. `9xx10^(-9) T`
D. `11xx10^(-11) T`

Answer

b

Explanation

Here, `E_(0)=18 V//m, B_(0)=?`
`:. B_(0)=(E_(0))/(c)=(18)/(3xx10^(8))=6xx10^(-8) T`
