Long, straight conductors with square cross section, each carrying current I , are laid side by side to form an infinite current sheet with current directed out of the plane of the page ( Fig. P28.74 ). A second infinite current sheet is a distance d below the first and is parallel lo it. The second sheet carries current into the plane of the page. Each sheet has n conductors per unit length. (Refer to Problem 28.73.) Calculate the magnitude and direction of the net magnetic field at (a) point P (above the upper sheet); (b) point R (midway between the two sheets); (c) point S (below the lower sheet). Figure P28.74

An alpha particle (consisting of two protons and two neutrons), traveling at a speed of v = 1.2 x 105 m/s, enters a region of constant magnetic field of strength B = 1.9 T as shown in the figure. The direction of B is out of the image. The alpha follows a path that is a circular arc of radius r.
In meters, what is the radius of curvature r of the path taken by the alpha particle?
