Homework Help: What is the magnitude of velocity of the proton?

  1. May 27, 2006 #1
    A proton source injects H(+) ions at low speed. A beam of protons (each having a rest mass 1.67*10^-27 kg) is moving in a circle of radius 80.0 cm between 2 circular flat electromagnets. If these electromagnets supply a force of 8.00*10^-13 N on each proton directed toward the center of revolution, what is the magnitude of the velocity of the protons? The proton motion is circular and the speeds involved are small compared with the velocity of light. Take the value of [tex]\sqrt 3.83 [/text] to be 1.96.

    You need to show your work, or atleast your plan of action, before we can help.
