Homework Question 13. A proton is shot at the nucleus of a gold atom. When the proton is a long way from the atom, its speed is 6 x106 m/sec. How far from the center of the nucleus is the turning point of the proton? (There is a periodic table in the appendix of your book.)
Some forms of tumors can be treated using proton therapy. The physics idea behind this
B.
biomedical technique is to design a machine that uses electric fields to accelerate a beam of protons
to high velocities. These high speed protons strike the tumor and destroy it by impact. One way to ac-
complish this is shown in the figure below where protons leak out with negligible speed from a hot
oven. The exit speed of these protons should be 1.0 × 106 m/s in the direction shown. The distance be-
tween the oven and plate B is given to be 5.0 m. The charge on a proton is 1.6 x 10-19 C and the mass of
a proton is 1.7 x 10-27 kg.
