PhysicsNEET 2021Force on a moving charge and on a current

Moving Charges and Magnetism

An infinitely long straight conductor carries a current of 5 A as shown. An electron is moving with a speed of m/s parallel to the conductor. The perpendicular distance between the electron and the conductor is 20 cm at an instant. Calculate the magnitude of the force experienced by the electron at that instant.

Question 3 as printed in the NEET 2021 booklet

  1. A. N
  2. B. N
  3. C. N
  4. D. N

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
