A point charge Q is placed on the x axis at the origin. An identical point charge is placed on the x axis at x = -1.0 m and another at x = +1.0 m. If Q = 20 μC, what is the magnitude of the electrostatic force on the charge at x = +1.0 m?
Two point charges are fixed on the y axis: a negative point charge q1 = -32 µC at y₁ = +0.21 m and a positive point charge 92 at y2 =
+0.38 m. A third point charge q = +8.2 µC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two
charges has a magnitude of 28 N and points in the +y direction. Determine the magnitude of 92.
