A charged particle with a mass of 9.11 x 10^-31 kg and a charge of +1.6 x 10^-19 C enters a magnetic field of 0.8 T with a velocity of 3.0 x 10^6 m/s at a right angle. Calculate the radius of the particle's circular path.
💡 Hint: Similar to previous calculations, plug in the particle's mass, charge, velocity, and magnetic field.
A velocity selector requires that particles move with a speed of 3.5 x 10^5 m/s. If the electric field strength is 5.0 x 10^4 N/C, what magnetic field strength is needed to keep particles undeflected?
💡 Hint: Quick rearrangement of the equation can help you find the value of B.
