1 magnetism!
two right rules.
num 1: thumb in direction of current, curl fingers, eletric field

perpendicular current and magnetic field

force on moving charge in a magnetic field \(\vec{F}=q\vec{V} \times \vec{B}\) q = charge V = velocity of charge B = magnetic field strength
\(q=1.6*10^{-19}\) \(\vec{b} = 5*10^{-5}T\) \(\vec{V} = 2000 \frac{m}{s}\) \((1.6*10^{-19})*2000 \times 5*10^{-5} = 1.6*10^{-20}\)
centripital force :: force acting to center force to curve something is given by \(F_c = \frac{mv^2}{R}\) solve for R: \(R = \frac{mv^2}{F_C}\)
mass of a proton: \(1.67 * 10^{-27}\)
plug in: \(R = \frac{1.67*10^{-27} 2000^2}{1.6*10^{-20}}=0.418m\)
