Which direction (with respect to the sheet of paper) does the force vector point for a proton that has a velocity to the left across the page through a magnetic field that is pointing into the page?

learn it on the intertant so you can solve

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
