Question 1

What is the motion of a charged particle in a magnetic field?

  • Linear
  • Circular
  • Elliptical

💡 Hint: Think about the force's direction.

Question 2

Increasing the velocity of a charged particle while keeping the magnetic field constant will decrease its circular path radius. True or False?

  • True
  • False

💡 Hint: Review the radius formula clearly.

Challenge Problems

Push your limits with challenges.

Question 1

An electron with a charge of -1.6 x 10^-19 C and mass 9.11 x 10^-31 kg enters a magnetic field of strength 1 T at an angle of 90° with a speed of 3 x 10^7 m/s. Calculate the radius of its path.

💡 Hint: Keep track of the signs; the charge affects direction but not radius in this case.

Question 2

If a charged particle takes 0.1 seconds for a full circular revolution in a magnetic field of 0.2 T, determine its mass if its charge is 1.6 x 10^-19 C.

💡 Hint: Rearranging formulas is key! Ensure to plug values carefully.
