Apositive charge q moves with velocity v in the +z direction (up out of the page) through a magnetic field whose vector is in the x direction.

the force fm will be in the:

a) positive-y direction
b) negative-z direction
c) positive-z direction
d) positive-x direction

Points toward +y direction

Explanation:

If a positively charged particle is moving in a magnetic field, an electromagnetic force occurs. The direction of this force is determined by applying right hand rule which explains like that; open four fingers of your right hand and point the thumb in the direction of the velocity and the fingers in the direction of Magnetic field ( B ). A perpendicular vector to the palm points in the direction of the force ( F ). In given drawing the perpendicular to the palm of right hand is + y direction.

Your correct answer is; positive-y direction
