a rectangle with sides parallel to the axis has one vertex at the origin and the opposite vertex on the curve y = Ax^N at the point where x = B (A > 0, N > 0, B > 0). Show that the fraction of the area of the rectangle that lies below the curve on the N but is independent on the A and B.
A line of charge along the y-axis has linear charge density +lambda from y = 0 to y= +a, and -lambda from y=0 to y=-a. I want to find an expression for the electric field at any point x along the x-axis It is noted that the charge configuration is similar in structure to a dipole. By symmetry, the x-components of the field cancel out, and the net field is in the y-direction. Here a = 1.5 m, lambda =...
