1. The problem statement, all variables and given/known data A two point charges (Qa and Qb) are placed along the y and x axis, as shown below: The Qa charge is placed 3 meters up from the y axis, which contains a -5.00 microcolumb charge. The Qb charge is placed 4 meters away from the x axis, which contains a 8.00 microcolumb charge. a. Calculate the net electric Field at the origin. 2. Relevant equations E-Field on Qa = kq/r^2 E-Field on Qb = kq/r^2 [c]3. Attempt of a solution[/b] E-Field on Qa = kq/r^2 = (9.0 E9 N m^2/C^2)(-5.00 E-6 C)/(3m)^2 = -5000 N/m E-Field on Qb = kq/r^2 = (9.0 E9 N m^2C^2)(8.00 E-6 C)/(4m)^2 = 4500 N/m Where do I go from here? Do I add the E-Fields or Find the Pythagorean Theorem to find the magnitude of the E-Field? Thanks. BTW...Dont worry Im not cheating...IM just asking a question that was asked on the midterm...that I didnt get the answer from.
