Question

Problem6 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 electric field at the origin points solely in the positive y direction If Q3 is released from rest, it wil initially accelerate to the right The force on Q3 due to the other two charges is zero The electric potential at any point along the y-axis is positive The electric potential at the origin equals Q314πε0d) (Here k-1/(4jeo) The external work done to bring these charges to this configuration (from infinity) was positive. The work required to move Q3 from its present position to the origin is zero Submit Answer Tries 0/6 b) In the previous problem, let Q1-240 μC.Q2-2.90 μC and Q3°3 30 C. (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 Answer Tries 0/6
