As a laudably skeptical physics student, you want to test Coulomb's law. For this purpose, you set up a measurement in which a proton and an electron are situated 921 nm from each other and you study the forces that the particles exert on each other. As expected, the predictions of Coulomb's law are well confirmed. You find that the forces are attractive or repulsive?     what is the magnitude of each force?

Two electrons in a vacuum exert force of F= 2.45E-08 N on each other. They are then moved so that they are separated by x = 5.1 times their original distance. How far apart in meters were the electrons originally?

Two electrons in a vacuum exert force of F = 4.63E-08 N on each other. They are then moved so that they are separated by x = 6.4 times their original distance. a.  What is the force, in newtons, that the electrons experience at the new separation distance?  b. How far apart, in meters, were the electrons originally?

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?…

THIS IS THE PREVIOUS QUESTION IT IS REFERRING TOO!! Your object has a mass of 35.6 kg. You separate an equal amount of protons and electrons into two boxes. You place the boxes at a distance of 80 m apart from one another. How much force attracts the two boxes to one another?                           Similar situation to the previous question, but now the object s mass is 60.0 kg and you initially put the boxes of protons and electrons 24 m apart. Now you want to take the two boxes and move them farther apart, to a new distance of 45 m apart. How much work (that is, energy) would you have to expend to pull the boxes that much farther apart, fighting against the electrostatic attraction between them?     1.44E+27 J     2.88E+27 J     5.76E+27 J     7.20E+26 J

An object has a mass of 13.6 kg. You separate the protons and electrons into two boxes like in the previous question. You place the boxes at a distance of 35 m apart from one another. How much force attracts the two boxes to one another?       1.24E+25 N     1.56E+24 N     3.11E+24 N     6.22E+24 N

A futuristic gun uses a strong electric field to accelerate small charged bullets to very fast speeds. The specially made bullets have a mass of 0.01kg and a hold charge of 0.1C. If the gun accelerates the bullets over a distance of 0.6m to a speed of vf = 10*m/s, what must be the strength of the electric field inside the gun? Give your answer in scientific notation with 2 or 3 significant digits.

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? Coulomb constant is 9 × 10⁹ Nm²/C². Answer in units of N. The T 06

You stand at location A, a distance d from the origin, and hold a small charged ball. You find that the electric force on the ball is 0.056 N. You move to location B, a distance 2d from the origin, and find the electric force on the ball to be 0.007 N. What object located at the origin might be the source of the field? (Select all that apply.)
