I'm still missing something. can you dumb it down more. do i use the formula my friend told me to use or do i ues another mass proton: 1.6*10^-27 charge of proton: 1.6*10^-19 C S= (0.5 E?*q?)/(1.6*10^-27((4.98 *10-6 C/m2)/(7.22 *106m/s))^2)

1. Homework Statement A proton traveling at a speed of 7.22 *106m/s enter the gap between the plates of a 7.86 cm wide parallel plate capacitor. The surface charge densities on the plate are ± 4.98 *10-6 C/m2. How far (in m) has the proton deflected sideways when it reaches the far edge of...

ya is that what i needed to use?

1. Homework Statement The electric field strength 7.79 cm from a very long charged wire is 2660 N/C. What is the electric field strength (in N/C) 12.7 cm from the wire? 2. Homework Equations E= (9*10^9) Q/ r^2 3. The Attempt at a Solution i have energy. so is tried to solve...
