Created by StemPy LabA student says: "A proton that moves faster takes less time to go once round its circle in the same field." What is wrong with this statement?
← All Quizzes
← A proton is sped up from rest through 2400 V and enters a magnetic field of 0.19 T at right angles. What is the radius of its circle?A proton and an alpha particle start from rest and are sped up through the same voltage. Then each enters the same uniform field at right angles. An alpha particle has twice the charge and four times the mass of a proton. What is the ratio of the radius of the alpha circle to that of the proton circle? →
