Question
Determine the force on an electron of charge 1.6×10⁻¹⁹C which is placed in a uniform electric field of 120,000V/m.
Correct Answer
Option B is the correct answer.
Detailed Explanation
F = qE = (1.6×10⁻¹⁹)(120,000) = 1.92×10⁻¹⁴N.
Hint
Apply F = qE directly using the electron's charge magnitude.
