## Homework Statement

I dont have any statement, i have to find the problem statement from the answers

a) E = Q / [ Eo* (0.020 m)^2 ]

b) a = E (1.60*10-19 C)/(1.67*10^-27 kg) = 2.0 *10^12 m/s^2

R=0,020 m

q=1.60*10-19 C

m=1.67*10^-27 kg

## Homework Equations

F=ma => a=qE/m

Gauss Law Integral of (E,ds)=Q/Eo

## The Attempt at a Solution

So given E constant everywhere i can assume that E*(integral of ds)=Q/Eo, so if this was a sphere it would be

4piR^2*E=Q/Eo so its out, my equation must be something like E*R^2=Q/Eo , so my area should be a a square ?,

also E and the trajectory of my q must be parallel right ?

Any helpful hints are really appreciated ;d
