AP Physics 2 - Magnetic Force

A proton is traveling parallel to a wire in the same direction as the conventional current. The proton is traveling at $66\frac{m}{s}$ . The current in the wire is . The proton and the wire are apart. Determine the magnetic force on the proton.

A circuit contains a battery and a $20\Omega$ resistor in series. Determine the magnitude of the magnetic force outside of the loop away from the wire on an electron that is stationary.

What is the force experienced by a $15\mu C$ charge moving at $6.2\cdot 10^7\frac{m}{s}$ through a magnetic field with strength at $48^{\text o}$ from perpendicular to the field?

A proton traveling at $1*10^7\frac{m}{s}$ in a horizontal plane passes through an opening into a mass spectrometer with a uniform magnetic field directed upward. The particle then moves in a circular path through $180^{\circ}}$ and crashes into the wall of the spectrometer adjacent to the entrance opening. How far down from the entrance is the proton when it crashes into the wall?

The proton’s mass is $1.67*10^{-27}kg$ and its electric charge is $1.6*10^{-19}C$ .
