Homework Statement
q=1.602*10^-19 point 1
L=1mm=r1
v=1.1*10^6 at point 2
F=1.44*10^-12 at point 1
Homework Equations
E=(1/4πε)*(q/r)
ΔV=∫E*dr=(1/4πε)*q∫(1/r)=(1/4πε)*q*ln (r2/r1)
ΔU=ΔK=mv^2/2
ΔK=mv^2/2=ΔV*q=q*(1/4πε)*Q*(ln(r2/r1))
Q=F/E=1.44*10^-12/(q(4*pi*epsilon*(1.00*10^-3)^2))=1.00*10^-9
The Attempt at a Solution
mv^2/2=ΔV*q=q*(1/4πε)*Q*(ln(r2/r1))r2=0.002m
IS this correct?
