Hello PF! How I've missed you! :)
Studying for a final that's in two days. Our prof skimped on the electricity/electron/unit thing. I don't even know what it's called! :(
I need to find the speed of an ion, as well as the magnitude of the magnetic force acting on it.
A Li+ ion,
m= 1.16E-26 kg
q= 1.60E-19 C
V (or EPE? Same thing?)= 400V
v= ?
B= 0.5 T
Is accelerated through a potential difference of 400V and enters a uniform magnetic field of 0.5T, perpendicular to the ion's velocity. Find v of the ion, find magnetic force acting on the ion.
I'm given the formulas (on a magical exam formula sheet)
q=Ne
EPE=qV
E=( kq) / r^2
F= ( kq1q2 ) /r^2
F=qE but don't have E...
F= qvBsin0 but don't have v.
Suggestions? I have a horrendous understanding of this unit... Our entire class is actually lost because of the lack of explanation on it :(
