Question

(a) Three point charges are placed along the y-axis, with charge ql -3 HC charge at (0,0,0) m, q2 --4-uC at (0,-4,0) m, and q3 -2 uC at (0,3,0) m. What is the net electrostatic force on q3? Answer:0.0045N0) (b) Two point charges are placed along the x-axis, with charge q 3 nC charge at (50,0,0) cm, and q2--4-nC at (0,0,0) cm. At what location along the x-axis, other than infinity, can another charge q3-2 nC be placed such that the net force on it is zero? Answer: x-+26.8cm (c) A charge ql 3 uC is located at the origin (0,0,0) while a second charge, q2-4 HC is located at (30,0,0) cm. Determine the magnitude and direction of the net electric force on a third charge q3 2 uC placed at (0,40,0) cm. Answer: Fnet-0.204N @ 212 degrees 2Please show all work:)
