Unformatted text preview: gas is W = 35 J and the heat added to the gas is W = . 63 J. Along path abc, the work done on the gas is W = 48 J. (a) What is Q for path abc? (b) If P c = P b =2, what is the work done on the gas W for path cda? (c) What is Q for path cda? (d) What is U a -U c ? (e) If U d -U c = 5 J, what is Q for path da? 5. A thin, non-conducting rod carrying a uniform linear charge density λ is bent into a semicircle of radius r. Find the electric field at the center of curvature of the semicircle. 6. Two electrons are rotating in opposite directions in circular orbits of radius r in a Bismuth atom. A magnetic field of 0.5 T is applied perpendicular to the plane of rotation of the electrons. Show that one electron is speeded up by the magnetic field by an amount Δω = eB /(2 m e 29 and the other is slowed down by the same amount, Δω . Calculate the new angular frequency of electron and the change in total magnetic moment resulting from the orbital motion of each electron....
