Q1. A rectangular conducting loop of wire is approximately half-way into a magnetic ?eld B (out of the page) and is free to move.

Suppose the magnetic ?eld B begins to decrease rapidly in strength. What happens to the loop?

Q2. The four tires of an automobile are inflated to a gauge pressure of 2.10E+5 Pa. Each tire has an area of 0.0267 m2 in contact with the ground. Find out the weight of the automobile.
