3. Each small sphere shown has a charge of magnitude q but the stationary charge in the center is negative while the two moving charges are positive. The moving charges (each of mass 0.20 kg) are attached to the ends of 4.0 m long strings and they are moving like conical pendulums as shown at a constant velocity of 12.0 m/s in uniform circular motion. The strings each make an angle of 30° to the vertical. Find the magnitude of the charge q. 300: 30° 4.0 m 4.0 m + q - 9 +q

m2 Two point charges (Q₁ = 2.1 µg) begin at rest a distance xo +01 = = 4.2 nC with mass mi 1.6 µg, and Q₂ 6.4 nC with mass 1.7 cm apart. Both are free to move. +Q₂ Xo = = Calculate the velocity of each charge at the moment charge Q2 has moved 1.0 cm.
Two equally charged, 1.00 g spheres are placed with 4.00 cm between their centers. 2 When released, each begins to accelerate at 225 m/s . As the spheres move, do you expect the force between them to increase, decrease or remain the same? Use an equation to justify your reasoning. Calculate the spacing needed between the spheres that would cut the force between them in half.

Two hard rubber spheres, each of mass m = 16.3 g, are rubbed with fur on a dry day and are then suspended with two insulating strings of length L = 5.50 cm whose support points are a distance d = 3.21 cm from each other as shown in the figure below. During the rubbing process, one sphere receives exactly twice the charge of the other. They are observed to hang at equilibrium, each at an angle of ? = 10.9° with the vertical. Find the amount of charge on each sphere. (Assume the two spheres have charges q1 and q2 = 2q1)
