Question

by using gass theorum find an electronic field intensity at a point at a distance r from an infinitely long uniform charge straight line
​

Answer 1

Answer:

Sorry i don't know i think it's very difficult

Explanation:

Leave it and go to next one

Answer 2

Answer:

According to Gauss theorem

Explanation:

Let the distance be r

a charge come for infinity

total field at any point P is radial

Let us consider a right circular cylinder

Electric flux and unit vector with angle 0°

E.ds = Eds cos 0°

E(2πrl)

charge enclose

q= linear charge density ×l

According to Gauss theorem

E= linear charge density

2π€• r

E is inversely proportional to r
