Consider an uncharged, conducting hollow spherical shell. The electric field on the inside surface of the spherical shell is measured to be directed toward the inner shell wall and varies in magnitude over the spherical shell's inside surface. It is known that the only charge in the hollow cavity inside the spherical shell is a point charge with magnitude q. What is the sign of the charge q?

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?
