A proton has an initial velocity of 7.6 × 106 m/s in thehorizontal direction. It enters a uniform electric field of 8800N/C directed vertically.
a) Ignoring gravitational effects, find the time it takes theproton to travel 0.127 m horizontally. The mass of the proton is1.6726 × 10−27 kg and the fundamental charge is 1.602 × 10−19 C .Answer in units of ns.
b)What is the vertical displacement of the proton after theelectric field acts on it for that time? Answer in units of mm.
c) What is the proton’s speed after being in the electric fieldfor that time? Answer in units of km/s.
