1. Suppose you cut off the compass into two and discarded one part. You drill a hole in the remaining part, and place the red part on the pivot at the center of the compass. Will it still work like a normal compass? 2. The figure below shows a uniform magnetic field directed into the plane of the paper (shown by the blue A particle with a negative charge moves in the plane. Which of the three paths-1, 2, or 3 does the particle follow? x x x x x x x Path 1 x x x x x x x *--*- Path 2 x x x Path 3
