An electron moving with a uniform velocity along the positive x-direction enters a magnetic field directed along the positive y-direction. The force on the electron is directed along
Positive y-direction
Negative y-direction
Positive z-direction
Negative z-direction
The direction of the force on a moving charge is given by right hand rule . Point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.
