5- Three charges True or False Y↓ a a J Q3 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.) For all multiple choice questions, consider the special case where Q₁, Q3 greater than zero and Q2 -Q₁. Please select all the statements that are true: If Q3 is released from rest, it will initially accelerate to the right. The electric field at the origin points solely in the positive y direction. The work required to move Q3 from its present position to the origin is zero. 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. The electric potential at the origin equals Q3/(4πted). (Recall that k = 1/(4πto)) 5b) In the previous problem, let Q₁=2.2µC, Q₂=-2.2 µC, and Q3=4 µC. (Note that Q₁ and Q₂ are different now.) The distances are a=1.2 cm and d=2.8 cm. Calculate the potential energy of the charge configuration. (Please answer in Sl unit)
