WebOn the other hand, if a sphere of radius R is charged so that the top half of the sphere has uniform charge density ρ 1 ρ 1 and the bottom half has a uniform charge density ρ 2 ≠ ρ 1, ρ 2 ≠ ρ 1, then the sphere does not have spherical symmetry because the charge density depends on the direction (Figure 6.21(b)).

If A = r , it corresponds to the area of a spherical cap (A = 2πrh) (where h stands for the "height" of the cap) and the relationship h/r = 1/2π holds. Therefore, in this case, one steradian corresponds to the plane (i.e. radian) angle of the cross-section of a simple cone subtending the plane angle 2θ, with θ given by: This angle corresponds to the plane aperture angle of 2θ ≈ 1.144 rad or 65.54°. snb tax certificate order onlineWebMar 24, 2024 · The solid angle Omega subtended by a surface S is defined as the surface area Omega of a unit sphere covered by the surface's projection onto the sphere.
