Hi can I have some help with these 4 questions please? Info:The effect of external magnetic and electric fields on moving protons in a vacuum jo investigate gated as described below. elow. Protons are produced at an anode and are accelerated from s an electric potential difference. The protons pass through a hole in a cathode a speed of 5.32 x 10^5m/s. Initially Setting :The magnetic field created by the current- Anode carrying coils has a strength of 0.034 T. The path of the proton beam becomes circular. There is no electric field in the region between the parallel plates. Second Setting :No change is made to the magnetic field.An electric potential difference is applied to the parallel plates. Third Setting :No change is made to the magnetic field. The electric potential difference is increased until the protons in the beam travel with uniform motion. 14. The magnitude of the electric potential difference between the anode and the cathode is A. 0.403 VB. 0.806C. 7.39x10^2D. 1.48x10^3

15. The the Initial Setting, which of the following wors Mientities the radius of the proton beam's path and the direction of the magnetic field? Path Row Radius Magnetic Field 0.16 m Direction B. 0.16 m Into the page DO C. 6.1 m Out of the page D. 6.1 m Into the page Out of the page 16. For the Second Setting, which of the following free-body diagrams, drawn to scale, best "hows the forces acting on a proton in the beam just as the proton enters the region containing the two perpendicular fields? A. B. F. 7 Use the following additional information to answer numerical-response question 3. Directions x 9 5 a 8 . 0 14 IT Numerical Response 3. For the Third Setting, the arrow given above that is closest to the direction of the electric field between the charged plates is numbered a. You will need to record the value of a. For the Third Setting, the magnitude of the electric field, expressed in scientific notation, is e.f x 108 N/C. You will need to record the values of e, f, and g. The values of a, e, f, and g are , and a g (Record all four digits of your answer in the numerical-response section on the answer sheet.)
