Answer:

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

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:

Answer:
my method is guessing it works 50% of the time :)
