The
magnetic field is coming out of the screen.
Force
on a charged particle due to a magnetic field is perpendicular to the
magnetic field direction.
As the proton entered from the left, the
Right-hand rule, shows the force on the proton was upward. As
the proton turns, the force remains perpendicular to the path of the
proton . The proton takes a
Counter-Clockwise path. The Correct
Answer is C. Right-hand rule
1. Fingers take the path of the positive particle.
2. Curve the fingers in the direction of the magnetic field.
3. The thumb points in the direction of the force on the positive
particle. Electrons and other
negatively charged particles use a Left-hand rule instead of a Right-hand
rule. |
