A proton is released from rest inside a region of constant, uniform electric field ?1 pointing due north. 34.8 s after it is released, the electric field instantaneously changes to a constant, uniform electric field ?2 pointing due south. 8.49 s after the field changes, the proton has returned to its starting point. What is the ratio of the magnitude of ?2 to the magnitude of ?1? You may neglect the effects of gravity on the proton.
