Application of Gauss’s Law: Finding the Electric Field outside a Uniformly Charged Solid Sphere of Radius ‘R’ and Total Charge ‘q’ Gauss’s law says that for this surface (for Gaussian surface) the electric field 𝐸 through any closed surface S (a Gaussian surface) is equal to the net charge enclosed (Q𝑒𝑛𝑐)divided by the permittivity of free space(𝜖0)
At last, Atomic Structure of a Glass have been Imaged Understanding the chemical element and 3D location of atoms in materials have been always at the forefront in the field of material science. The atomic …
