- Homework Statement
- The diagram shows two charges, +4 µC and -16 µC, 120 mm apart. What is the distance from the +4 µC
charge to the point between the two charges, where the resultant electric potential is zero?
A 24 mm
B 40 mm
C 80 mm
D 96 mm
- Relevant Equations
- f=kq1q2/r^2
This question is a bit werid because would there be a resulatant electric potential equal to zero as we have a positive and negative charge in which case there's no neutral point. As E1-E2 , they have to be acting in oppostie directions , in this case would they be acting in the same direction.
