If the magnitude of the electric field 0.65 m from the axis of the cylinder is 4500 N/C what is R, (the radius of the cylinder), in meters?

: In a box you find objects that come in three different colors: Green, Yellow, andPink. You’re told that each color corresponds to a charge state, either positive (+), negative (-), orneutral. You experiment and find that…Green is attracted to Yellow. Yellow is attracted to Pink Green is repelled by Green. Pink is repelled by Pink.What colors are the charged (either positive or negative) objects? What color is neutral object?

Current Attempt in Progress How much work is required to set up the four-charge configuration of the figure if q = 1.32 pC, a = 56.5 cm, and the particles are initially infinitely far apart and at rest? Number Units J O

1. If I draw a Gaussian surface surrounding the nucleus of an Oxygen atom, with an atomic number of 8, what is the electric flux through that surface? If I increase the size of that surface to enclose the entire atom, i.e., include the electrons too, what is the electric flux through the surface? What is the electric flux if the Oxygen atom oxidizes to 0²-?

[Numbers change] In the early 1900's Robert Millikan discovered the peculiar property that charge came in little packets, no smaller than e = 1.602 x 10-19 C -- he had measured the charge of the electron. Here's (roughly) how he did it. He removed an electron from an initially neutral droplet of oil with diameter 0.8 um. In a vacuum, he positioned the droplet between two metallic plates separated by 4 mm and fiddled with the potential (voltage) across the plates until the droplet would hover against the force of gravity. Droplets of this size with +e charge would hover, but only for a particular voltage (otherwise they would sink or rise). Given the parameters stated here, and the fact that the density of the oil was 815 kg/m³, what was the voltage that made the droplets hover? (give your answer with 0.1 V precision)
