Mas le'ingPhysics: Homework #3x e The Bacleriurn E. Culi Is A S ingle https://session.masteringphysics.com/myct/itemView?assignmentProblemiD-97706006 PHYS 207 Fall 2018 Ashley Homework #3 Problem 4.60 12 of 12 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. The ions are fired directly toward the center of the tumor at speeds of 4.7 x 10 m/s To cover the entire tumor area, the ions are deflected sildeways by passing them between two charged metal plates that accelerate the lons perpendicular to the direction of their inital motion. The acceleration region is 5.0 cI long, and the erids of the acceleration plates are 1.5 III from the patient. (Figure) Part A What sldeways acceleration is required to deflect an lon 2.0 cm to one slde? Express your answer to two significant figures and include the appropriate units. Figure

Explanation / Answer

Time taken before accelerating

t1= d/s= 0.05/(4.7*10^6)= 1.064*10^-8 s

Time taken to reach patient

t2= 1.5/(4.7*10^6)= 3.3*10^-7 s

Velocity along horizontal,

Vx= 0.02/(3.3*10^-7)

Vx= 6.27*10^4 m/s

Now acceleration is given by

a= vx/t1

= 6.27*10^4/(1.067*10^-8)

= 5.873*10^12 m/s^2

Comment in case any doubt.. good luck
