Question

triply ionized particles in a beam carry a net positive charge of 3 elementary charge units, the beam enters a magnetic field of 4.0*10^-2T the particles have a speed of 9.0*10^6m/s

Answer 1

What is the magnitude of the force acting on each ion?

$F=qvB\sin\alpha=$

$=(3\cdot1.6\cdot10^{-19})\cdot9\cdot10^6\cdot4\cdot10^{-2}\cdot\sin90°=173\cdot10^{-15}\ (N)$ . Answer
