Homework Equations
Fe = q*Ee
The Attempt at a Solution
a)
dx = vx*t
0.0682 = 4.92*106 * cos(68) * t
t = 0.0682 / [4.92*106 * cos(68)]
= 3.70036*10-8 seconds
dy = dyi + vy*t + at2
0 = 0 + 4.92*106 * [0.0682 / [4.92*106 * cos(68)]] * sin(68) + a * [0.0682 / [4.92*106 * cos(68)]]2
a = -4.92*106 * [0.0682 / [4.92*106 * cos(68)]] * sin(68) / [0.0682 / [4.92*106 * cos(68)]]2
= -1.23278 * 1014 m/s2
mass of electron = 9.10938291 * 10-31 kg
charge of electron = 1.60217657 * 10-19 C
Fe = ma
= 9.10938291 * 10-31 * [ -4.92*106 * [0.0682 / [4.92*106 * cos(68)]] * sin(68) / [0.0682 / [4.92*106 * cos(68)]]2 ]
Ee * q = Fe
Ee * 1.60217657 * 10-19 = 9.10938291 * 10-31 * [ -4.92*106 * [0.0682 / [4.92*106 * cos(68)]] * sin(68) / [0.0682 / [4.92*106 * cos(68)]]2 ]
Ee = 9.10938291 * 10-31 * [ -4.92*106 * [0.0682 / [4.92*106 * cos(68)]] * sin(68) / [0.0682 / [4.92*106 * cos(68)]]2 ] / (1.60217657 * 10-19)I got part b correct, so I must have the correct acceleration - now I can't figure out where I'm going wrong.
