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.
Acceleration is defined as the rate of change in the speed of a moving body or vehicle typically.
<u>Explanation:</u>
In the branch of mechanics, the aspect of acceleration is considered to be a property of the vector. And acceleration always occurs in a specific positive direction.
The formula for determining acceleration is change in the rate of velocity over a specific time, and is therefore measured as the ratio of delta velocity by delta time unit.
The unit of acceleration is distance per time unit squared or m / second squared.
