Three magnetic compasses are placed at the corners of a horizontal equilateral triangle. as in any ordinary compass, each compass
needle is a magnetic dipole constrained to rotate in a horizontal
plane. in this case the earth’s magnetic field has been precisely
annulled. the only field that acts on each dipole is that of the other
two dipoles. what orientation will they eventually assume? (use
symmetry arguments! ) can your answer be generalized for n compasses at the vertices of an n-gon?

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?
