With what constant speed v does the bar slide along the rails? that can slide without friction on a pair of rails separated by a distance 1.20 m and located on an inclined plane that makes an angle 9-33.0° with respect d a uniform magnetic field of magnitude B 0.500 T is directed downward, perpendicular to the ground, over the entire region through which the bar m/s Submit Answer Save Progiess Practice Another Version My Notes Ask Your

Explanation / Answer

F = B I L sin phi = B (E / R) L sin phi

induced emf E = B v L sin phi

F = B (B v L sin phi / R) * L * sin phi

F = B2 v L2 sin2phi / R

m g sin theta = B2 v L2 sin2phi / R

0.260 * 9.8 * sin 33 = 0.52 * v * 1.22 * sin257 / 2.2

v = [0.260 * 9.8 * sin 33 * 2.2] / [0.52 * 1.22 * sin257]

v = 12.0 m/s
