Three positive and equal charges Q1, Q2, and Q3 are at the corners of an equilateral triangle. Point P is at the midpoint of the line between Q1 and Q3 (the middle of the bottom of the equilateral triangle). The electric field at P is A.zero b. not zero and directed along the line from P to Q3 c.not zero and is directed along the line from P to Q2 d. not zero and is directed along the line from Q1 to Q2 E.none of these are correct My thinking is that the answer is zero. I know that the electric field points away from positive charges so if Q1 and Q3 are at the bottom of the equilateral triangle the P is in the middle they are going to direct the opposite way and cancel each other out. Anybody know if this is correct or have a reason why another answer would be correct?
