An infinite line of charge with charge density λ1 = 0.6 μc/cm is aligned with the y-axis.
what is ex(p), the value of the x-component of the electric field produced by the line of charge at point p which is located at (x, y) = (a,0), where a = 7.5 cm?

1440 × 10⁴ N/C

Explanation:

Data provided in the question:

Charge density λ1 = 0.6 μC/cm = 6 × 10⁻⁵ C/m

a = 7.5 cm = 0.075 m

Now,

Electric field due to a line charge at a distance 'a' is given as:

Ex(P) =

also,

we know

= 9 × 10⁹ Nm²/C²

Thus,

we have

Ex(P) =

therefore,

Ex(P) =

= 1440 × 10⁴ N/C

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

hope this ! this is not copied! search it up, it's free of plagiarism!

c) power lifting, will be your answer.
