Q1. A 35 g horizontal metal bar, 11 cm long, is free to slide up and down between two tall, vertical metal rods. A 5.0×10-2 T magnetic field is directed upright to the plane of the rods. The bar is raised to near the top of the rods, and a 1.2 Omega resistor is connected across the two rods at the top. Then the bar is dropped. What is the terminal speed at which the bar falls? Imagine the bar remains horizontal and in contact with the rods at all times.

Q2. A short coil with radius R = 11.00 cm contains N = 27 turns and surrounds a long solenoid with radius r = 9.00 cm containing n = 49 turns per centimeter. The current in the short coil is increased at a constant rate from zero to i = 2.47 A in a time of t = 13.00 s. compute the induced potential difference in the long solenoid even as the current is increasing in the short coil.
