Question 1

What is the condition for a charged particle to move in a straight line when both electric and magnetic fields are present?

  • The net force is zero.
  • The electric field is zero.
  • The magnetic field is zero.

💡 Hint: Think of the implications of balanced forces.

Question 2

True or False: A velocity selector can filter charged particles based on their electric charge.

  • True
  • False

💡 Hint: Consider the primary function of the velocity selector.

Challenge Problems

Push your limits with challenges.

Question 1

A proton moves through a magnetic field of 0.3 T and has an electric field of strength 1000 N/C acting on it. Calculate the velocity of the proton required for it to move in a straight line.

💡 Hint: Use the relationship that allows you to solve for velocity.

Question 2

If a velocity selector is set to filter particles at a speed of 200 m/s, what electric field strength is required if the magnetic field is 0.2 T?

💡 Hint: Think about how the electric field relates to the velocity of the particles.
