Pick out the wrong statement.
- A An electron at rest experiences no force in the magnetic field
- B The gain in the KE of the electron moving at right angles to the magnetic field is zero
- C When an electron is shot at right angles to the electric field, it traces a parabolic path
- D An electron moving in the direction of the electric field gains KE
Answer & Solution
Correct Answer
(D) An electron moving in the direction of the electric field gains KE
Step-by-step Solution
Detailed explanation
Electron is negatively charged, hence experiences electrostatic force opposite to the direction of electric field. As a result, an electron moving in the direction of electric field loses kinetic energy.
