A schematic drawing of a rail gun. Projectile P sits between two wide rails of
circular 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, r
the radius of each rail, and i the current. Find the expression for force on the along the
