Challenge Problems
Push your limits with advanced challenges
A charged particle enters a magnetic field with a velocity making a 30-degree angle with the field direction. If the magnetic field strength is 0.2 T and the charge is +1 C, calculate the force exerted if the velocity is 5 m/s.
💡 Hint: Don’t forget to consider the sine of the angle!
An electron moves in a magnetic field of 0.1 T with a speed of 2 × 10^7 m/s. Calculate the force on the electron, knowing the charge of the electron is -1.6 × 10^-19 C.
💡 Hint: Use the absolute value for force magnitude!
