Solve the all parts of following question:
Question: In a mass spectrometer, a beam of protons enters a magnetic field. Some protons make exactly a one-quarter circular arc of radius 0.50m.
Part A: If the field is always perpendicular to the proton's velocity, what is the field's magnitude if exiting protons have a kinetic energy of 8.0keV?
Part B: How long does it take the proton to complete the quarter circle?
I want help to find how long it takes the proton to complete the quarter circle and express your answer using two significant figures.
Find the value of Q that would make the thickness of the equivalent body 0.1 times its length (i.e the value of y at the dividing streamline at x=0 is 1/10 of the x coordinate at the aft stagnation point.).
