The electric field a distance z from the center of a uniformly charged solid disk of radius R is (Edisk) z = 1 2€0 1 √z²+R² where n = Q/(R²) is the (constant) surface charge density of the disk. What is the limit of (Edisk) where z << R and why? O It is equal to n/(20), the electric field near an infinite plane, since the disk looks like an infinite plane for points very close to the disk. It is equal to n/(2€0), the electric field near an infinite plane, since the disk looks like a point charge for points far away from the disk. It is equal to n/(20), the electric field of a point charge, since the disk looks like a point charge when very far away from the disk. It is equal to Q/(4π€02²), the electric field of a point charge, since the disk looks like an infinite plane when very close to the disk. It is equal to Q/(47€022), the electric field of a point charge, since the disk looks like a point charge when very close to the disk. I DON'T KNOW YET
