    I know the template needs to be used but i dont want answers i need help starting this. What equation do i use?


    Here is the question:


    In a particular region of space, the magnetic and electric fields have energy densities of 0.2 J/m3 and 4
    J/m3 , respectively. Calculate the strength of the magnetic and electric fields in this region
