Question

Problem 6 a) In the picture below, the 3 charges Q1, Q2 and Q3 are located at positions (-a,0), (a,0) and (0,-d) respectively (The origin is the point halfway between Q1 and Q2.) 2 Consider the special case where Q1, Q3 greater than zero and Q2 Q1 Select true or false for each statement. The work required to move Q3 from its present position to the origin is zero The electric potential at the origin equals Q3/(4πε0d) (Here k = 1/(4πεο)) The electric field at the origin points solely in the positive y direction The external work done to bring these charges to this configuration (from infinity) was positive. The force on Q3 due to the other two charges is zero. The electric potential at any point along the y-axis is positive. If Q3 is released from rest, it will initially accelerate to the right. Subnmit Answer Tries 0/6 b) In the previous problem, let Q1-1.50 μC, Q2-2.80 μC' and Q3-4.00 1C. (Note that Q1 and Q2 are different now.) The distances are a-1.20 cm and d-2.80 cm Calculate the potential energy of the charge configuration Submit AnswerTries 0/6
