Question

state guass's law in electrostatics and applying guass's law derive an expression for electric intensity due to an infinite long straight charged wire
​

Answer 1

Answer:

Solution : Gauss. law in electrostatics states that the total electric flux overa closed surface in free space is `(1)/(in_(0))` times the net charge enclosed within that surface. Mathematically, for a closed surface <br> `phi_(E)=ointvecE. hatn ds = (1)/(in_(0))(Q)` where Q = total charge enclosed.
