The distance between the two charges is 
Explanation:
The electrostatic force between two charged objects is given by Coulomb's law:

where:
is the Coulomb's constant
are the charges of the two objects
r is the separation between the two charges
In this problem, we are given the following:



Therefore, we can rearrange the equation to solve for r, the distance between the two charges:

Answer:
<h3>4</h3>
Explanation:
VR = Velocity ratio = Distance moved by effort/Distance moved by load
Given:
Distance moved by effort = 20m
Distance moved by Load = 5m
VR = 20/5
VR = 4
Hence the velocity ratio of the car is 4
