Question

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

Options:

A . 4× 10−6 T

B . 6× 10−8 T

C . 9× 10−9 T

D . 11× 10−11 T

Answer: Option B
:
B

c = \frac{E}{B} \Rightarrow B = \frac{E}{c} = \frac{18}{3 \times 10^{8}} = 6 \times 10^{- 8} T .
