A 01-M-Long Rod Rotates About a Perpendicular Axis at One End

question 83

Multiple Choice

A 0.1-m-long rod rotates about a perpendicular axis at one end. As the rod rotates, it passes through a uniform magnetic field that has a perpendicular component of 3 *10^-2 T to the plane of rotation. If the induced EMF across the ends of the rod is
0) 2 V, then calculate the number of revolutions per second of the rod.

• A) 6.7 * 10¹ revs/s
• B) 6.7 *10³ revs/s
• C) 4.7*10^-3 revs/s
• D) 6.7*10² revs/s
• E) 2.1 *10² revs/s
