In a certain region of space there is a uniform magnetic field pointing in the positive z direction (+z). In what direction should a negative point charge move to experience a force in the positive x direction (+x)?
1.in the positive z direction (+z) 2.in the negative z direction (–z) 3.in the positive x direction (+x) 4.in the negative x direction (–x) 5.in the positive y direction (+y) 6.in the negative y direction (–y) 7.It can move in any direction. 8.It is impossible for the force to be in the +x direction when the magnetic field is in the +z direction.
