Final answer. (a) Consider two infinite parallel plates with uniform charge densities. Describe a configuration (in terms of charges on each plate) that would result in the electric field being zero everywhere outside the plates. (b) Extend your reasoning to three parallel plates.The question: Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities $\sigma_1$,$\sigma_2$,$\sigma_3$ and $\sigma_4$ on their surfaces, as shown in the following figure. Φ = 𝜎A/ε 0 (eq.2) From eq.1 and eq.2, E x 2A = 𝜎A/ε 0. Therefore, E = 𝜎/2ε 0. The direction of an electric field will be in the outward direction when the charge density is positive and perpendicular to the infinite plane sheet. The direction of an electric field will be in the inward direction when the charge density is negative ...Homework Statement. Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities a,b,c,d on their surfaces. These surface charge densities have the values a= -6.00 nC, b= +5.00 nC, c= +2.00 nC, and d= +4.00 n\C. Find the magnitude of the electric field at the point C, in the middle of the right-hand sheet.

The charge density is the measure of the accumulation of electric charge in a given particular field. The following are some of the dimensions in which the charge density is measured: Linear Charge Density: \ [\lambda = \frac {q} {l} \] , where q is the charge and l is the length over which it is distributed. The SI unit will be Coulomb m-1.Science. Advanced Physics. Advanced Physics questions and answers. (20%) Problem 5: Two large rectangular sheets of charge of side L=2.0 m are separated by a distance d=0.025 m. The left and right sheets have surface charge densities of 19.1μC/m2 and −6.6 μC/m2, respectively. A proton is released from just above the left plate.In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. Induced Charge and Polarization: Field lines change in the presence of dielectrics.
