Randall D. Knight — Kinematics in Two Dimensions: Problem Problem_62

You are asked to consult for the city’s research hospital, where a group of doctors is investigating the bombardment of cancer tumors with high-energy ions. As FIGURE P4.62 shows, ions are fired directly toward the center of the tumor at speeds of \(5.0 \times 10^6\text{ m/s}\). To cover the entire tumor area, the ions are deflected sideways by passing them between two charged metal plates that accelerate the ions perpendicular to the direction of their initial motion. The acceleration region is \(5.0\text{ cm}\) long, and the ends of the acceleration plates are \(1.5\text{ m}\) from the target. What sideways acceleration is required to deflect an ion \(2.0\text{ cm}\) to one side?
