Electric field at surface of sphere
WebThe potential and electric field distributions implied by (13) are illustrated in Fig. 5.9.2b. If q exceeds q c 12 o E a R 2, the entire surface of the sphere is covered with positive surface charge density and E is directed outward over the entire surface. WebApr 7, 2024 · Here, the radius R expresses the charge distribution while the radius r is the radius of the Gaussian surface. The electric field needs to be directed radially, and the angle between the electric field and area vector is 0 or (cosθ = 1). However, when the angle between the area vector and electric field is 180° or (cosθ = 0).
