gaws low for electrostatic and it's application for infinite plane sheet and infinite long straight wire answer
Hello
Gauss's Law and its applications :
The total electric flux through a closed surface is proportional to the enclosed charge.
Applications :
1. Infinite Plane Sheet of Charge :
For a sheet with surface charge density , using a pillbox Gaussian surface, the electric field .
2. Infinitely Long Straight Wire :
For a wire with linear charge density , using a cylindrical Gaussian surface, the electric field at distance .
hope this helps you .
