How many coulombs are represented by 3.2 × 1020 electrons?

6 AV + A₁ C₁=1pF C₂=2μF C3 = 3µF AV = 6V C₁ C- C3 (a) Find the charge on C₁ in Micro-Coulombs (input the num the answer box).

Does a positive charge outside a conductor induce only the free electrons to move, so there are no positive charges that are actually moving due to repulsion?

In a salt crystal, the distance between adjacent sodium and chloride ions is 2.8×10−10×10−10 m. What is the force of attraction between the two singly charged ions?

The ink drops have a mass mmm = 1.00×10−11 kg each and leave the nozzle and travel horizontally toward the paper at velocity v = 15.0 m/s. The drops pass through a charging unit that gives each drop a positive charge q by causing it to lose some electrons. The drops then pass between parallel deflecting plates of length D0D0D_0 = 2.15 cm, where there is a uniform vertical electric field with magnitude E = 7.70×104 N/C.  1) If a drop is to be deflected a distance d = 0.340 mmmm by the time it reaches the end of the deflection plate, what magnitude of charge q must be given to the drop? Assume that the density of the ink drop is 1000 kg/m3 , and ignore the effects of gravity.
