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?

• physics -

the square shape is for mu.....

• physics -

Potenial at each point: kQ/r

work= differencein potential* distance y to X.

difference in potential= PotentialY-PotentialX

The closer is the higher potential
