An electron with mass 9.11×10-31 kg moves with a speed of 1.90×106 m/s in a circle of 2.63 cm radius under the influence of a magnetic field. A proton of mass 1.67×10-27 kg , moving in the same plane with the same speed, experiences the same centripetal force. What is the radius of the proton's orbit?
