A charge of moves at perpendicular to a magnetic field of . What is the magnetic force on it (in N)?

Answer and explanation

Correct answer: B. 200

  1. Step 1: State the magnetic Lorentz force magnitude on a moving charge: .
  2. Step 2: For perpendicular motion (, ), substitute charge , speed , and magnetic field : .
  3. Step 3: Compute force: .
Answer
200.
Why not the others: The alternative options (10, 100, 40) result from neglecting fundamental physical conservation laws, misapplying physical constants, or arithmetic calculation slips.
