A positive charge is moving vertically upwards. When it enters a region of magnetic field directed towards north, the direction of force on the charge would be
- A East
- B West
- C North
- D South
Answer & Solution
Correct Answer
(B) West
Step-by-step Solution
Detailed explanation
By the right-hand rule for positive charges: fingers point upwards (\( \vec{v} \)), curl towards north (\( \vec{B} \)), thumb points West. Direction of force: West
