Questions 30-31A magnetic field of 1 T causes a proton beam of 2 mA to move in a circle with a radius of 0.1 m. Assume that the magnetic field is perpendicular to the plane that the circle is located on.30.What is the best estimate of the work done in Joules on the protons in each orbit of the complete circle?
31.What is the best estimate of the speed of a single proton in this beam of protons moving in a circle due to the magnetic field?
32.Shown above there is an electron moving to the right undeflected by both the electric field in between the plates and the magnetic field coming out of the page in between the plates. The magnetic field has a magnitude of 2.0 T and the electric field has a magnitude of 8 N/C. What is the speed of the electron?
33.A particle with a negative charge has an initial velocity that is parallel to a magnetic field moving to the right. What path would this negatively charged particle follow?a.Parabolic arcb.Spiralc.Circular arcd.Straight line parallel to the field
