Question: In a certain reference frame a static, uniform, electric field E 0 is parallel to the x axis, and a static, uniform, magnetic induction B

In a certain reference frame a static, uniform, electric field E₀ is parallel to the x axis, and a static, uniform, magnetic induction B₀ = 2E₀ lies in the x-y plane, making an angle θ with the axis. Determine the relative velocity of a reference frame in which the electric and magnetic fields are parallel. What are the fields in that frame for θ << 1 and θ → (π/2)?
