Question 21: Calculate the ratio of the Coulomb force to the gravitational force, Fc/Fg, between two protons separeted by a distance d. Does the ratio change if the distance d changes from 10-10 m to 100 km?

In the figure, if Q = 15 µC, q = 2.4 µC, and d = 29 cm, what is the magnitude of the electrostatic force on q?

There are two identical, positively charged conducting spheres fixed in space. The spheres are 45.4 cm apart (center to center) and repel each other with an electrostatic force of F = 0.0645 N. A thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed, the spheres still repel, but with a force of F2 = 0.115 N. The Coulomb force constant is k = 1/(4En) = 8.99 × 10º N · m²/C². Using this information, find the initial charge on each sphere, q and q2, if q1 is initially less than q2 . 91 = 92 =

Wouldn't the Proton being 1.5 cm from the Positive Plate and 3.5 cm from Negative Plate effect the magnitude of the force?

Consider the point charges arranged at the corners and at the center of a square, as depicted in the figure. a)Find the magnitude of the net Coulomb force, in newtons, on the charge q in the figure, given that q = 1.2 μC, qa = 2.8 μC, qb = -4.4 μC, qc = -5.9 μC, and qd = 1.7 μC. The square is 34 cm on a side.

Two point charges have a value of 30 uC each and are 4 cm apart.  What is the electric field at the midpoint between the two charges?

At the points of the angles of an equilateral triangle with a side length of 30 cm, the electric charges are 2uC, 2 uC, and 3uC, respectively. What is the coulomb force experienced by a 3uC charge? (with pictures) PLEASE HELP SIR, STEP BY STEP, WITH PICTURE, THX.
