With colored pen; draw five equipotential lines, three of which must pass through each of points A,B_ and C, You mustdraw the equipotential lines perpendicular to every electric field line that they intersectwith: Next, find three additional points on your equipotential lines One should have the same potential as A,another the same potential as B, the last the same potential as C. Label these points A* B* , and C* respectively.
Conceptually.whatis value for the potential difference between and B*?
Answer
Using measurements and
we will calculate the potential difference between and B .
First calculate the potential at A due to the positive charge, this should be positive value in volts. You will meed to measure positive distance from the center of the positive charge to point A
Next, calculate the potential at due negative value in volts: Again; measure tne negative charge to point A
tne negative charge This should be positive distance from the center of
Finally; add these two values together to get the total voltage (or potential) at A:
Answer =
