alleryThe magnetic force on a negative charge, compared with a positive one, is:
AOpposing
BOptional
COriginal
DOpposite
Answer & Solution
Correct answer: D. Opposite
1. The sign of the charge enters the force directly.
2. Force on a negative charge is opposite to that on a positive charge.
3. So the correct answer is opposite.
