Answer:

$3.33\cdot 10^(-8) T$

Step-by-step explanation:

For an electromagnetic wave, the relationship between magnetic field amplitude and electric field amplitude is given by

E=cB

where

E is the amplitude of the electric field

c is the speed of light

B is the amplitude of the magnetic field

For the electromagnetic wave in this problem, we have

E = 10 V/m is the amplitude of the electric field

So if we solve the formula for B, we find the amplitude of the magnetic field:

$B=(E)/(c)=(10 V/m)/(3\cdot 10^8 m/s)=3.33\cdot 10^(-8) T$
