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
