You have a hoop of charge of radius R and total charge -Q. You place a positron at the center of the hoop and give it a slight nudge. Due to the negative charge on the hoop, the positron oscillates back and forth. Use VPython to find the force on a positron a distance d=0.13mm above a center of a ring of R=5.2cm and charge Q=-3.7×10-9C. Use this result as a reasonableness test for this HIP. Print out an include your program with what you turn in.
