The plane of a square loop of wire with edge length is oriented vertically and along an east- west axis. The earth's magnetic field at this point is of magnitude and is directed northward at below the horizontal. The total resistance of the loop and the wires connecting it to a sensitive ammeter is . If the loop is suddenly collapsed by horizontal forces as shown in figure, what total charge enters one terminal of the ammeter?
