Point X and Y are 30.0 mm and 58.0 mm away from a charge of +8.0 C.
a. How much work must be done in moving a +2.0 C charge from point Y to point X?
b. What is the potential difference between points X and Y?
c. Which point is at the higher potential?

the square shape is for mu.....

Potenial at each point: kQ/r
work= differencein potential* distance y to X.
difference in potential= PotentialYPotentialX
The closer is the higher potential
