The figure above shows four very thin parallel planes of charge with equal separation between them. The charge density on plate 1 is 5 σ. The charge density on plate 2 is -3 σ. The charge density on plate 3 is 2 σ. The charge density on plate 4 is -1 σ. Your answers for the electric field must include the correct sign. We choose positive electric field along the positive x-direction. What is the Electric Field at point D? (in units of σ/ε0)

A parallel plate capacitor of capacitance C with plates at separation d, has charge Q. The electric field at a distance r from positive plate between the plates isChoose answer:

Two uniform infinite sheets of charge density +σ and –σ intersect at right angles. Electricfield due to this configuration at any point in space is

The energy density in the electric field of a parallel plate capacitor with charge 𝑄Q and capacitance 𝐶C is given by:a) 𝑄22𝐶2CQ 2 ​ b) 𝑄2𝐶CQ 2 ​ c) 𝑄24𝐶4CQ 2 ​ d) 𝑄28𝐶8CQ 2 ​

The figure below shows two lines of charge in cross-section coming out of the page. Each line of charge has a linear charge density of ±3.30 nC/cm and they are separated by a distance d = 19.5 cm. What is the magnitude of the electric field at the dot, a point y = 6.70 cm above the midpoint between the lines?

Three conducting plates are given 3Q, –2Q and Q charge as shown in figure. After distribution of charge find value of q1, q2, q3, q4, q5 and q6.
