Question
For problem 14 of the text calculate the velocity in m/s using a Hall voltage of 4.49 microvolts. (5 sig figs)
**Problem 14:** A metal strip 6.50 cm long, 0.850 cm wide, and 0.760 mm thick moves with constant velocity \( \vec{v} \) through a uniform magnetic field \( B = 1.20 \, \text{mT} \) directed perpendicular to the strip, as shown in Fig. 28-34. A potential difference of \( 3.90 \, \mu \text{V} \) is measured between points \( x \) and \( y \) across the strip. Calculate the speed \( v \). **Figure 28-34 Explanation:** The diagram shows a rectangular metal strip moving upward with velocity \( \vec{v} \). This strip is placed in a magnetic field \( \vec{B} \), indicated by \( \times \) symbols (representing the direction into the page). Points \( x \) and \( y \) are marked on the strip, demonstrating the potential difference across the width of the strip. --- **Problem 15:** A conducting rectangular solid of dimensions \( d_x = 5.00 \, \text{m} \), \( d_y = 3.00 \, \text{m} \), and \( \ldots \)
