Question
Please Provide Full Explanation
Two charges q1 and q2 separated by a distance d produce a potential V = 0 at point P. (The potential is taken to be zero at infinity). Which of the following statements is true? No force would act on a test charge placed at P. The net work needed to bring a test charge from infinity to point P is zero. If q1 as already in place, the work required to move q2 from infinity to a point a distance d from q1 is zero. The electric field at point P is zero q1 and q2 must be of the same sign but of different magnitudes.Explanation / Answer
Answer is B.
The net work done to bring a test charge from infinity to Point P is zero because the work done is the defference in potential energy which should equal to 0.
