The wire in the figure has linear charge density λ.What is the electric potential at the center of the semicircle?Give your answer in terms of λ, R, ε0, and appropriate constants.
A piece of thin, non-conductive wire is bent into a semicircle of radius r. It is then charged with a uniform linear charge density lambda. Integrate to find the electric potential at the center of the (half) circle.
A semicircular plastic wire of radius R has a uniform linear charge density λ. A point charge Q is placed at the center of the semicircle. What force does it feel? Give the magnitude and direction.
A charged wire of negligible
thickness has length 2L units and has a linear charge density
lambda. Consider the electric field E-vector at the point P, a
distance d above the midpoint of the wire.

A wire having a uniform linear charge density λ is bent into the shape shown in the figure below. Find the electric potential at point O.
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 =...
