- An infinite wire (R = 0.05 c m) is charged to λ = 2.5 μ C / c m. An electron is knocked out of the wire. Right at the edge, the electron flies outward at 6 × 10 7 m / s. How far does it travel before it stops and returns?A small metal sphere, carrying a net charge of qt= +7.5 mC, is held in a stationary position by insulating supports. A second small metal sphere, with net charge of 2' +3 mC and mass 2 g is projected toward q . When two spheres are 0.8 m apart, sa is moving toward qt with speed 22.0 mls, see Figure. Assume that the two spheres can be treated as point charges. Neglect the force of gravity. a) What is the speed ofqt when the spheres are 0.5 m apart† How close can q2 approach to q1 ?You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 2.8 g mass from it. This stretches the spring to a length of 5.1 cm . You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.3 cm . What is the magnitude of the charge (in nC) on each bead?
- Charges in static electricity are typically in the nanocoulomb (nC) to microcoulomb (μC) range. What is the voltage 5.00 cm away from the center of a 1-cm diameter metal sphere that has a −3.00 nC static charge?A particle with a charge of -60.0 nC is placed at the center of a nonconducting spherical shell of inner radius 20.0 cm and outer radius 23.0 cm. The spherical shell carries charge with a uniform density of -3.31 µC/m3. A proton moves in a circular orbit just outside the spherical shell. Calculate the speed of the proton. 6.644e4 Your response is off by a multiple of ten. m/s5 3 Part a and b are correct. I need help with c and d.

- Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting -50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 31 steps? charge buildup from 31 steps: How many electrons are present in that amount of charge? electrons present: nC maximum number of steps: electrons If a delicate manufacturing process can be damaged by an electrical discharge greater than 1012 electrons, what is the maximum number of complete steps that any worker should be allowed to take before touching the components? stepsThe charge in the bottom right corner of the figure is Q = -90 nC. What is the magnitude of the electrical force on Q?Two electrons in an atom are separated by 1.6 × 10-10 m, the typical size of an atom. What is the force between them?
