- Three infinite uniform sheets of charge are located in free space as follows: -7 nC/m2 at y = 3, -4 nC/m2 at y = -4, and 9 nC/m2 at y = 0. Find magnitude of E at the point PA(9, 14,-7).arrow_forwardThe density seen in the figure is 4pi Coulomb charge uniformly (evenly everywhere) distributed along the surface of the 2m radius disc. According to this, 1. Find the charge density on the disc surface. 2. Find the electric field that will occur at the point 2m above the axis of the charge.arrow_forwardTwo 1.20 m non-conductive wires form a right angle. A segment has +2.50 µC of charge, distributed evenly along its length; while the other segment has -2.50 µC of charge, distributed uniformly along its length, as illustrated in the figure. Find the magnitude and direction of the electric field produced by these wires at point P, which is 60.0 cm from each wire.arrow_forward

- Hey I was wondering if you can help me with this problem plz Figure shows a plastic rod with a uniform charge −Q. It is bent in a 120° circular arc of radius r and symmetrically placed across an x axis with the origin at the center of curvature P of the rod. In terms of Q and r, what is the electric field E ⃗ due to the rod at point P?arrow_forwardElectrostatics Two bidirectionally infinite line charges exist in vacuum. One has a charge density of -7 nC/m at x = -8, y = -8, while the other has a charge density of 9 nC/m at y = -4, z = -8. Determine the y-component of the electric field in V/m at (1, 1, 5). All coordinates are measured in meters.arrow_forwardThe charge densities of the 2 layers are given in the figure. These layers are perpendicular to the z-axis and the distance between them is d. both layers extend to infinity in the x and y directions, and their thickness is negligibly small. Take the electric potential as 0 at the starting point.Draw equipotential surfaces.arrow_forward
