A straight rod of length =22.80 cm carries a uniform charge density =1.80×10^−6 C/m. The rod is located along the ‑axis from 1=0.00 to 2=. The Coulomb force constant is =8.99×109 N·m2/C2.
A vertical line of positive charge of length capital L. A labeled point P is located above the line of charge along a line coaxial with the line of charge. The distance from the base of the line of charge to point P is y subscript zero, with y sub zero greater than L.
Find the expression for the electric field along the ‑axis at a point P. What is the magnitude of the electric field at 0=60.00 cm?
