A stick with a varying linear charge density of λ = (14 - 1x) nC/m lays on the x axis from x = 6 m to 10 m. Find the electric field and the electric potential at point P, at the origin, x = 0 m. Note that λ is no longer a constant! Note that the charge density is 8 nC/m when x = 6 m

A positive charge is evenly distributed on the surface of a metal sphere centered at the origin of the coordinate system. The positive charge produces an electric field that points outwardly in the radial direction. A positive test charge is fixed at a distance R₁ from the center of the coordinate system, far from the surface of the sphere. The electric potential at R₁ is 10V. The positive test charge is then allowed to move freely until it reaches a distance R₂=2R₁ from the center of the coordinate system. What is the electric potential (in Volts) of the test charge at its new resting point? 10

A line of charge with a non-uniform charge density λ (lambda) = ay, where a=−10 nC/m2 lies along the y axis with one end at the origin and the other at y=h, where h=4.7 m Given that the total charge is -110.45 nC, calculate the electric potential of this line of charge at point P on the x axis a distance 0.7 m from the origin. Assume the potential equals zero at infinity
