- Positive charge is distributed with a uniform density λ along the positive x-axis from r to ∞, along the positive y-axis from r to ∞, and along a 90° arc of a circle of radius r, as shown below. What is the electric field at O? (Use the following as necessary: λ, r, and ε0.) E = _____ i + ______ j + ______ kA uniform electric field of magnitude 43.1N/C is parallel to the x axis. A circular loop of radius 25.7cm is centered at the origin with the normal to the loop pointing 27.4 above the x axis. A). Calculate the electric flux in, newton squared meters per coulomb, through the loop. B). To what angle, in degrees from the positive x axis, should the normal of the loop be rotated so that the flux through the loop becomes 0.419N⋅m2/C?S: x 0' R 4x Note: Figure not drawn to scale. The figure above shows a thin, circular nonconducting sheet of positive charge uniformly distributed over its area. The radius of the sheet is R. Point O is at the center of the sheet. Point S is a distance x from the center of the sheet, and point T is a distance 4x from the center of the sheet. Assume R>>x if the magnitude of the electric field at point T is ET, which of the following best represents the magnitude of the electric field at point S?
