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.

E = 1.655 x 10⁷ N/C towards the filament

Explanation:

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

E = " alt="\frac{\lambda}{2\pi\times\epsilon_0\times r}" />" />

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 =

E = 1.655 x 10⁷ N/C

0.19 m/s and 0.45 m/s
