Question

How can you direct the fired proton's path downward?

Answer 1

Answer:

The correct answer is "Place a proton above the original path".

Explanation:

Proton pathways are used in different physical applications for medical and diagnostics systems such as  proton-computed tomographies and other radiologies. A way to modify a fired proton's path downwards in these systems is to place another proton above the original path. Protons repel each other in the opposite direction for having the same charge, therefore, a proton placed above the path of another proton would change its path downward.

Answer 2

Answer:

B. Place a proton above the original path

Explanation:

Like charges would repel one another. Unlike charges would attract.

When the proton is placed above the original path, it repels the fired proton and thereby goes downward.
