Point charges q1 = 50 μC and q2 = −25 μC are placed 1.0 m apart. What is the force on a third charge q3 = 20 μC placed midway between q1 and q2 ?

Two point charges are fixed on the y axis: a negative point charge q1 = - 28 μC at y1 = + 0.15 m and a positive point charge q2 at y2 = + 0.35 m. A third point charge q = + 9.2 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 23 N and points in the +y direction. Determine the magnitude of q2.

Three point charges are fixed as shown in (Figure 1). Take q₁ = 20 μC, q2 = -30 μC, 93 = 40 μC, and d = 9.0 mm. The point charge of 3.6 μC is placed at the center of the triangle.

Two point charges are placed on the x axis. A charge of qA= +4.54 μC is placed at x= 0 and a charge of qB= -2.87 μC is placed at x=d. When a third point charge qC is placed at x= 2.29d, the electric force on the charge at x= 0 doubles in magnitude but maintains its original direction. What is qC?

Two charged spheres on a frictionless horizontal surface are attached to opposite ends of a string & are in static equilibrium. The 39 kg red sphere has more charge than the 22 kg green sphere. The total charge magnitude on the spheres is 120 ?C & they have the same polarity. As a result the tension is 202.5 N & the centers of the spheres are 0.39 m apart. Find the charge magnitude on each sphere. Qred (bigger charge) = Qgreen (smaller charge) =
