For problem 9, solve for the magnetic field (in mT) when the accelerating voltage remains 1000 V and the voltage difference between the voltage deflection plates (the "horizontal" par with one above the other in the picture) is 85.7 V. (5 sig figs)
**Figure 28-32 Problem 9:** In Figure 28-32, an electron is accelerated from rest through a potential difference \( V_1 = 1.00 \, \text{kV} \) and enters the gap between two parallel plates. The separation between the plates is \( d = 20.0 \, \text{mm} \), and there is a potential difference \( V_2 \) across the plates. **Diagram Explanation:** - The diagram consists of an electron initially at rest, shown as a red dot. - It moves along the x-axis, as indicated by the arrow pointing to the right. - The electron first passes through a region with a potential difference \( V_1 \). - It then enters a region between two parallel plates with separation \( d \) and potential difference \( V_2 \). **Chapter 28: Magnetic Fields** **Problem Context:** Given \( \vec{B} = (30.0 \, \text{mT}) \hat{\jmath} \), referring to Figure 28-35, determine: (a) the resulting electric field within the solid, expressed in unit-vector notation. (b) the potential difference across the solid.
