Two point charges of and are separated by a distance of in vacuum. At what distance from the positive charge on the line joining the two charges is the electric potential zero?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: C —
Solution
The electric potential is zero when . Substituting the values $4/x = 2/(1-x)$ leads to $4 - 4x = 2x$, which simplifies to $6x = 4$, so .
