- 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 25 steps. How many electrons are present in that amount of charge?Two balloons (m = 0.022 kg) are separated by a distance of d = 12 m. They are released from rest and observed to have an instantaneous acceleration of a = 1.1 m/s2 toward each other at the moment they are released. Assume the two balloons are point charges and have equal but opposite charges. Part (a) Calculate the magnitude of the charge on each balloon in C. Part (b) How many electrons are responsible for the charge, N?Two parallel plates of charge (+) and (-) are placed with a distance of d = 5 mm (see picture). The charge density of each plate is the same, namely 17.7 μC/m². A positive charge q = +3 nC with mass m = 30 x 10^-30 kg is released from rest starting from the left plate. What is the kinetic energy of this charge when it arrives at the right plate?

Part (b) Write an equation for the electric field dE at point P due to the thin slide of the rod dx. Give your answers in terms of the variables Q, L, x, a, dx, and the Coulomb constant, k. Notice that the coordinate x will be less than zero over the length of the rod. Part (c) Integrate the electric field contributions from each slice over the length of the rod to write an equation for the net electric field E at point P. Part (d) Calculate the magnitude of the electric field E in kilonewtons per coulomb (kN/C) at point P due to the charged…Two uncharged, conducting spheres are separated by a distance d. When charge −Q is moved from sphere A to sphere B, the Coulomb force between them has magnitude F0. Is the Coulomb force attractive or repulsive?

- Let's say two unknown charges are given to you. You do not know their individual charges, but you know that their total charge is 8.00µC. You made a test in the laboratory and found that these two charges push each other away with a force of 0.150 N when separated by 0.500 m. What is the charge of the "higher charge" in units of µC ?In part (a) of the figure an electron is shot directly away from a uniformly charged plastic sheet, at speed vs = 3.60 x 105 m/s. The sheet is nonconducting, flat, and very large. Part (b) of the figure gives the electron's vertical velocity component v versus time t until the return to the launch point. What is the sheet's surface charge density? Assume ts = 28.0 ps. (a) v (105 m/s) t (ps) (b)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?…
