A proton initially moves left to right long the x axis at a speed of 9,070 m/s. It moves into an electric field, which points in the negative x direction, and travels a distance of 0.7 m before coming to rest. If the proton's mass and charge are 1.67 × 10−27 kg and 1.60 × 10−19 C respectively, what is the magnitude of the electric field?
The electric field is zero everywhere except in the region 0≤x≤4.00 cm, where there is a uniform electric field of 110 N/C in the +y direction. A proton is moving in the +x direction with a speed of v = 1.00×10^6 m/s.
