Answer:0.15 m/sec
Explanation:
To calculate speed you use distance over speed
18.3/122= 0.15
Sometimes in the same direction but most of them go in the opposite direction
<h2>Hello!</h2>
The answer is: Coulomb's law equation.
<h2>Why?</h2>
The Coulomb's law states that the strength of an electric field (between two charges) can be calculated by multiplying their charges and dividing it into the square of the distance between their centers.

Where:
E = Electric Field Strenght


d = separation between charges (m)
Have a nice day!
