Answer:
C) at right angles to the direction of the motion
Explanation:
The magnetic force exerted on a charged moving particle is given by
where
q is the charge of the particle
v is the velocity of the particle
B is the magnetic field intensity
is the angle between the direction of v and B
Moreover, the direction of the force is perpendicular to both v and B. In particular, the direction can be found by using the right hand rule:
- index finger: direction of the velocity
- middle finger: direction of the magnetic field
- thumb: direction of the force (if the charge is positive, otherwise the direction must be reversed if the charge is negative)
