5.A schematic drawing of a rail gun. Projectile P sits between two wide rails ofcircular cross section; a source of current sends current through the rails and through the(conducting) projectile (a fuse is not used). (a) Let d be the distance between the rails, rthe radius of each rail, and i the current. Find the expression for force on the along therails and is given approximatelySourceLDVIf the projectile starts from the left end of the rails at rest, find the speed v at which it is expelledat the right. Assume that i =525 kA, d=9.7 mm, r= 8.2 cm, L=5.4 m, and the projectile mass is12 g.

Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.
