Question

draw a Gaussian surface in order to calculate the electric field at p and mark direction of electric field at this point​

Answer 1

Explanation:

its ok and that solve

1. we draw gaussian surface is cylinder
2. as we know that we draw gaussian surface according to their symmetry

Answer 2

Answer:

The Gaussian surface of the infinitely long straight wire is attached, which is a closed imaginary surface.

Explanation:

Gauss's law is the law that states the flux through any closed surface and the net charge enclosed within the surface. The total flux of the electric field E over any closed surface is equal to 1/ε₀ times the net charge enclosed by the surface, ϕ= q/ε₀

​The closed imaginary surface is called the Gaussian surface. This law tells us that the flux of E through a closed surface S depends only upon the value of the net charge inside the surface and not on the location of the charges and the charges outside the surface will not contribute to flux.

The Gaussian surface is attached.
