- Protons With Initial Kinetic Energy 9 0 10 15 J Enter A Region Of Uniform Magnetic Field Shaded In The Figure At Time 1 (76.16 KiB) Viewed 83 times
Protons with initial kinetic energy 9.0×10−15 J enter a region of uniform magnetic field (shaded in the figure) at time t=0 moving in the direction shown. The magnetic field has a magnitude 0.010 T. The protons undertake a half circle motion, then exit the region of the magnetic field. (a) (3 marks) What is the speed of the protons? (b) (4 marks) What is the direction of the magnetic field? (Justify your answer). (c) (3 marks) Calculate the radius of the half circle of the protons' path in the magnetic field.
