How far apart must two protons be if the Coulomb force between them is equal to the weight of a single proton at the earth's surface? Assume that the two protons are far removed from any other charges. The charge of the proton is 1.60x10 -19 C, and its mass is 1.67x10 -27 kg.

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity of 0.200 rev/s . The angular acceleration is 0.911 rev/s^2 . Its blades form a circle of diameter 0.720m . A) Compute the angular velocity of the fan after time 0.201 s has passed. Express your answer numerically in revolutions per second

Hi. Can someone please explain to me what exactly the electric potential is and how it differs from electric potential energy -- not with equations, but in prose. (Or at least, with both.) I can read the equation, but I don't really understand what electric potential IS. What is its significance? Thank you!

Four quick conceptual questions: 1) Is the electric field (E = -delta V / delta s) always a positive number (or zero)? That is, is it always the absolute value of the magnitude of the electric field? Or can it have a negative value? 2) Is electric potential (delta V) always negative? The answer to one of the questions in m

Two positive chrages, when combined, give a total charge of +8.7 micro Couloumbs. When the charges are seperated by 3.00 meters, the force exerted by one charge on the other has a magnitude of 8.30E-3 Newtons. Find the amount of each charge.

An electric dipole is constructed out of two point charges of equal magnitude q and opposite signs, separated by a distance d, as shown in the attached diagram. Find the electric field at the point P. The two charges are each a distance r from point P.

Two identical small charged spheres, each having a mass of 3X10^-2kg, hang at equilbrium. The length of the string is .2m, the angle between each string and the perpendicular is 10 degress. A=.034M A) What is the tension in the string B) Electric force felt by each sphere C) Charge of each sphere D) If the spheres were neg

1) Given: V = αx2y2 + βz2(x2 - γ) + δy3z Where α = 5 V/m4, β = 6.6 V/m4, γ = 3.4 m2, and δ = 5.3 V/m4. What is the y component of the electric field Ey at (4.6m, -4 m, 4.7 m)? Answer in units of V/m. 2) The electric potential in a certain region is:

Find the ratio of the electric force to the gravitational force between two electrons.

Each of two small spheres is charged positively, the combined charge being 5 x 10^-5 C. If each sphere is repelled from the other by a force of one newton, when the spheres are two meters apart, how is the total charge distributed between the two spheres ?

See attached file. 1. An electron is released a short distance above Earth's surface. A second electron directly below it exerts an electrostatic force on the first electron just great enough to cancel the gravitational force on it. How far below the first electron is the second? 2. Three charges are arranged as shown in

Two identical metal balls bear the same amount and sign of electric charge because they have been touched together. The mass of each ball is 2.00 grams. One ball is mounted on an insulating post. The other ball is suspended from a bifilar silk thread suspension system so that it can move on a 0.500 meter radius. When the two
