Measuring the Charge. You and your team are designing an experiment where two spherical insulating beads of diameter 0.45 cm and mass 0.15 g are strung together on a fine thread that passes through microscopic holes drilled through their centers. When hung vertically, the lower bead rests on a knot at the bottom of the thread and the upper bead rests upon the lower bead. When placed inside a vacuum chamber and exposed to X-rays (highly energetic electromagnetic radiation), the beads acquire equal, uniform distributions of positive charge on their surfaces due to the loss of electrons ejected when struck by the X-rays. During this experiment, the beads are hung vertically, and a gap forms between them as if the top bead were levitating above the lower one, presumably due to the repulsive electrostatic force between them. The gap, that is, the vertical separation between the top of the lower bead and the bottom of the upper bead, is 0.27 cm. (a) How much excess charge is on each bead?…
In the figure three identical conducting spheres initially have the following charges: sphere A, 6Q: sphere B, -8Q; and sphere C, 0. Spheres A and B are fixed in place, with a center-to-center separation that is much larger than the spheres. Two experiments are conducted. In experiment 1, sphere C is touched to sphere A and then (separately) to sphere B, and then it is removed. In experiment 2, starting with the same initial states, the procedure is reversed: Sphere C is touched to sphere B and then (separately) to sphere A, and then it is removed.

Two identical point loads are aligned horizontally. The load on the right is attached to a support and the one on the left is attached to a rope attached to the ceiling at a point directly above the load on the right. The charges are 50 cm apart, and each charge has the following characteristics: m = 2 g and Q = 1 µC. Calculate the height h, in cm, between the loads and the ceiling if the system is at equilibrium. Use g = 9.81 m/s2 in your calculations.

The gecko is sticking upside down to a smooth ceiling. The remarkable adhesion might be due to static electricity. Gecko feet are covered with microscopic hairs. When these hairs rub against a surface, charges separate, with the hair developing a positive charge and negative charge forming below the surface. There is an attractive force between the separated charges. This is an effective means of adhering to a surface, but it comes at a cost: Two planes of charge are like two charged plates of a capacitor, which takes energy to charge. Doubling the amount of charge on each surface increases the attractive force, but also increases the energy required to separate the charge. Part A By what factor does this energy increase?

A small plastic ball with a mass of 6.5 x 10-3 kg and with a charge of +0.15 uC is suspended from insulating thread and hangs between the plates of capacitor. The ball is in equilibrium with the thread making an angle of 30 degrees with respect to vertical. The ball is displaced by 0.15 m from its vertical position. What is the magnitude of the electric field between the two plates?
A light, unstressed spring has length d. Two identical particles, each with charge q, are connected to the opposite ends of the spring. The particles are held stationary a distance d apart and then released at the same moment. The system then oscillates on a frictionless, horizontal table. The spring has a bit of internal kinetic friction, so the oscillation is damped. The particles eventually stop vibrating when the distance between them is 3d. Assume the system of the spring and two charged particles is isolated. Find the increase in internal energy that appears in the spring during the oscillations.
A point charge, q = -5.0 nC, and m = 2.0 x 10-18 kg, is shot vertically upward with an initial speed of 3.0 x 105 m/s from a thin, infinite, planar sheet of uniform charge with surface charge density of σ = +4.0 nC/m^2 . To what vertical elevation will q rise above the sheet of charge? Neglect gravity
Three identical conducting spheres denoted as X, Y, and Z are separated in space. They have initial net charges of −2Q, −3Q, and 5Q, respectively. Sphere Z is touched to X and separated, then touched to Y and separated. Upon reaching electrostatic equilibrium, what is the final net charge of Y?
A 8-g charged plastic sphere charged to 75 µC is on top of a plastic spring with spring constant k = 400 N/m, which has a relaxed length of 10 cm. You then place another charged object 1 cm above (not touching) the sphere. Now, the spring is 9.5 cm long. Find the charge on the new second object.
A small metal sphere carrying a net charge of Q = -2.00 uC is held stationary by insulating supports. A second small metal sphere with a net charge of Q 2 = +7.80 uC and mass 1.50 g is is held 0.8 m away from the center of the first sphere. Assume the two spheres can be treated as point charges and that you can ignore gravity. If the second sphere is released, how fast will it be traveling when it is 0.6 m away from the center of the first sphere?
