On being charged the spheres, which were originally in contact, take up positions with their centers 5 cm apart. 2003-2023 Chegg Inc. All rights reserved. Determine the charge on each balloon. If the charges have the same sign, the Coulomb force is repulsive, separating the balls a distance \r" away from each . $$. Answer: Consider the figure given below. If a plastic rod rubbed with fur is made to touch two small pith balls (now-a-days we can use polystyrene balls) suspended by silk or nylon thread, then the balls repel each other [Fig. The Tibetan dZi vintage imitation glass beads necklace on the original cotton thread strand with mixed metal silver spacer beads. Ah I see, Thanks. If the spheres are first brought into contact and then separated to the original distance, then the ratio of the new force to the previous force is Two equal small spheres each weighing 1g , hang by two equal silk threads from the same point. Metal sphere A of radius 12.0 cm carries 6.00 C of charge, and metal sphere B of radius 18.0 cm carries 4.00 C of charge.
