Question

The charge per unit length on a long, straight filament is -92.0 μC/m. Find the electric field 10.0 cm above the filament.

Answer 1

E = 1.655 x 10⁷ N/C towards the filament

Step-by-step explanation:

Electric field due to a line charge is given by the expression

E =
`[tex](\lambda)/(2\pi*\epsilon_0* r)`[/tex]

where λ is linear charge density of line charge , r is distance of given point from line charge and ε₀ is a constant called permittivity and whose value is

8.85 x 10⁻¹².

Putting the given values in the equation given above

E =
`(92*10^(-6))/(2*3.14*8.85*10^(-12)*10^(-1))`

E = 1.655 x 10⁷ N/C
