A conducting sphere with a radius of 0.25 m has a total charge of 5.90 mC. A particle with a charge of −1.70 mC is initially 0.35 m from the sphere's center and is moved to a final position 0.48 m from the sphere's center.
a. What is the difference in electric potential between the particle's final and initial positions, ΔV = Vf − Vi?
b. What is the change in the system's electric potential energy?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?
