Answer:
The potential difference between the points is: 0.1 V
Step-by-step explanation:
Given
To determine
The potential difference between the points is
We can use the formula to determine the potential difference between the points

where W is done by moving charge q₀ from point A and point B
substituting W = 2J, and q₀ = 20 C

V
Therefore, the potential difference between the points is: 0.1 V
