A proton initially moves left to right along the x-axis at a speed of 2.00 x 103 m/s. It moves into an uniform electric field, which points in the negative x direction, and travels a distance of 0.200 m before coming to rest. If the proton's mass and charge are 1.67 x 10-27 kg and 1.60 x 10-19 C respectively, what is the magnitude of the electric field?
