Easy Question- cant seem to get it

  1. Dec 10, 2007 #1
    1. The problem statement, all variables and given/known data
    What is the magnetic field amplitude of an electromagnetic wave whose electric field amplitude is 100V/m?



    2. Relevant equations
    Eo=Bo*c


    3. The attempt at a solution

    100/(3*10^8) = .0000003

    Mastering physics says this is wrong though ^^

    That looks fine to me. Now express this as a decimal.
