An infinite line of charge, with a charge density 1, lies along the y-axis as shown in the figure below. Also shown in the figure is a rectangle with side lengths a and d that is parallel to the yz-plane and centered on the x-axis, and is located at x = 1/20. Z d a 1/2ay X Find an expression for the flux through the rectangle in the figure above. When constructing expressions use: linear charge density 1 use lambda rectangle side length a use a rectangle side length d use d Permittivity constant 20 use epsilon
