Homework Statement


At a particular instant a proton is traveling in the +z direction, with speed 4105 m/s. At the location of the proton there is a magnetic field of magnitude 0.25 T in the +x direction, due to current running in a nearby coil.
what is the direction and magnitude of force on the proton?

Homework Equations


none i think?


The Attempt at a Solution


Do you use the right hand rule possibly?

The right hand rule can give you the direction of the force, but not the magnitude.

What equation do you know that gives the force on a charged particle of charge q moving with velocity v in a magnetic field of strength B?

Try to find out the formula for the force on a charged particle in a magnetic field. The direction of the field is given by the left hand rule.

the equation is F=qvB but then using the left hand rule since it is a proton would give me negative y direction if I'm not mistaken and that is incorrect?

You can use either right handed screw rule or Flemming's left hand rule.
