Question

A point charge is placed at the center of a spherical Gaussian surface. The electric flux is changed: A. if the sphere is replaced by a cube of the same volume Explain B. if the sphere is replaced by a cube of one-tenth the volume C. if the point charge is moved off center, but still inside the original sphere D. if the point charge is moved to just outside the sphere E. if a second point charge is placed just outside the sphere

Answer 1

Answer:

Explanation:

Point charge is Placed at the center of a spherical Gaussian surface and according to Gauss law electric flux through Gaussian surface is given by $\frac{1}{\epsilon _0}$ times the charge enclosed

where $\epsilon _0=$permittivity of free space

So unless we take charge outside of the surface flux will not change for the Gaussian surface

So Statement A,B,C and E are false

Option D is correct because we take the charge outside of the Gaussian surface
