An infinite line of charge has a uniform linear charge density ??? = 1.50 ?C/m. A section of the line is shown below. Calculate the absolute potential at point P when the zero point (V = 0) is set at r = 3.50 m. The electric field due to a uniformly charged line is given by: E = 2k? / r P r = 1.50 m k = 8.99×10^9 Nm^2C^-2

A line of charge starts at $x=+x_{0}$ and extends to positive infinity. The linear charge density is $\lambda=\lambda_{0} x_{0} / x$ Determine the electric field at the origin.
An infinite line charge of uniform linear charge density lambda = -2.4 μC/m lies parallel to the y-axis at x = -1 m. A point charge of 1.9 μC is located at x = 1.0 m, y = 2.0 m. Find the x-component of the electric field at x = 2.0 m, y = 1.5 m.
