A disk of radius R=7.52 cmR=7.52 cm is centered at the origin and lies in the y-zy-z plane. The disk has a surface charge density σ=5.88×10−6 C/m2.σ=5.88×10−6 C/m2. Evaluate the electric field E(x)E(x) produced by this disk along the x-x- axis at point P=(1.19 cm,0.00 cm).P=(1.19 cm,0.00 cm). The Coulomb force constant k=1/(4π0)=8.99×109 N·m2/C2.
