Find the charge densities before/after the plates are brought together. Thanks! What is the magnitude of...
Two very large thin conducting plates with the same magnitude charge, but opposite sign, are held near each other. The plates are large enough and close enough together that fringing effects near the edges can be ignored (that is results of the Gauss' law for "infinite" plate apply) The two plates are a distance D apart. The surface area of the face of each plate is A, the total charge on each plate is and -o, and the resulting uniform...
In class, I argued that for two (conducting) charged plates with respective charge densities ±Q/A we can add their fields to find the overall field strength due to two parallel charged plates. While that is the correct result I want you to show that this indeed the case by considering the following scenario with conducting sheets of finite thickness: (a) Take one negatively charged plate and add an uncharged conducting slab of equal dimension across from it such that they...

Two large parallel conducting plates separated by 7 cm carry equal and opposite surface charge densities such that the electric field between them is uniform. The difference in potential between the plates is 200 V. An electron is released from rest at the negatively charged plate.

Answer number 2 using the given hints. Thanks
1. For the given capacitor, there are conducting plates at z = 0 and 2 = 3d. Between the plates, there are 3 layers of insulators: 2 free space regions and one dielectric with permittivity e. The electric field in Region 1 is E = - a, (V/m), where Ps is the surface charge density on the top plate ( = 30). The surface area of each plate is A. (a) What...
what is b plz
. Consider a disconnected parallel plate capacitor with area Ao and width --4, 3do. There is a magnitude of charge density g, on each plate. For this problem you may assume the plates are large enough to neglect fringing fields. 3d How much energy is stored in the capacitor?2 z a. For the purpose of simplifying the math, assign this value 3E. A large conducting slab of area A and width do is now placed within...
Three very large parallel non-conducting planes (infinte planes) have surface charge densities of sigma,-sigma a and -3sigma (sigma > 0). Planes are distance d apart from each other. The origin of the coordinate system was set on the first plane as shown in the figure. Planes are perpendicular to z axis. Point A is 1/2 d away from the origin while point B and P are 2 d and 4 d away from the origin respectively. a) Use Gauss's law,...
igure below shows two thin nonconducting plastic sheets with uniform charge densities, parallel to e other. (The sheets are very large and very close to each other, so at the locations stated below, you may approximate them as infinite.) The left sheet's charge per area is σ, while the right sheet's is-σ (where σ > 0), what is the magnitude and direction of the electric field at the locations specified below? (Use any variable or symbol stated above along with...
