Two balloons filled with air are each tied to very light 0.5-m-long strings. The loose ends of the strings are taped to the same position on a horizontal bar. When both are equally rubbed with the same material they both develop a static charge and repel each other making an angle of 30º with respect to the vertical. Note: the mass of a rubber balloon is not given! If you find/assume a mass, cite a source!
(a) With this experiment alone can you tell what type of charge is on the balloon? Explain.
(b) Is this a stable or unstable equilibrium? Why?
(c) Estimate the number of excess charges on each balloon. Clearly state any assumptions made in your estimation.
(d) If a small charged sphere is placed in the middle of the two balloons and the angle between them doubles, estimate the number of excess charges on the sphere, again being sure to state any assumptions used in your calculation.

Two balloons each have mass 4.0x10 kg. Balloon 1 has a negative net charge. Balloon 2 has twice the net negative charge of balloon 1. Balloon 1 is taped to the wall, and balloon 2 is tied to a string of length 0.70 m, which is attached to the ceiling directly above balloon 1 as shown. In the final equilibrium situation, the string makes a 20 degree angle away from balloon 1, and the two balloons are at the same...
You rub two 4.0-mg balloons with a wool sweater. The balloons hang from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of 37?with the vertical. Represent the situation with the force diagram for each balloon and determine the magnitudes of the forces that the balloons exert on each other. Will the relative magnitudes change if the charge on one balloon is two times...
You rub two 2.0-g balloons with a wool sweater. The balloons hang from 0.50-m-long very light strings. When you attach the strings together at the top, the balloons hang away from each other each string making an angle of 37∘ with the vertical. Determine the magnitude of the electric force between the two charges?

Two hard rubber spheres, each of mass m = 15.0 g, are rubbed with fur on a dry day and are then suspended with two insulating strings of length L = 5.00 cm whose support points are a distance d = 3.00 cm from each other as shown in 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 θ =10.0o with...
Two small metallic spheres, each of mass m-0.25 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ-4.80 with the vertical. If each string has length L 38.0 cm, what is the magnitude of the charge on each sphere?
Two small metallic spheres, each of mass m-0.40 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of θ = 7.5° with the vertical. If each string has length L 28.0 cm, what is the magnitude of the charge on each sphere? nC
Two small metallic spheres, each of mass 0.20 g, are suspended as pendulums by light strings from a common point as shown in the figure below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of 5.0° with the vertical. If each string is 30.0 cm long, what is the magnitude of the charge on each sphere?
Two metal spheres, each of mass 0.55 g, are suspended by massless strings from a common pivot point at the ceiling, as shown in the figure. When both spheres carry the same electric charge, we find that they come to an equilibrium when each string is at an angle of θ = 4.0° with the vertical. If each string is 26 cm long, what is the amount of the charge on each sphere? (Enter the magnitude in nC.)
