Question: What is the electric field at a distance r from an infinitely long line charge with linear charge density λ?

Options:

Correct Answer: λ/2πε₀r

Solution:

The electric field due to an infinite line charge is given by E = λ/2πε₀r.

What is the electric field at a distance r from an infinitely long line charge with linear charge density λ?

Step 1: Understand that an infinitely long line charge has a uniform charge distributed along its length.
Step 2: Identify the linear charge density, λ, which is the amount of charge per unit length.
Step 3: Recognize that the electric field (E) created by this line charge depends on the distance (r) from the line.
Step 4: Use the formula for the electric field due to an infinite line charge, which is E = λ / (2πε₀r).
Step 5: Note that ε₀ is the permittivity of free space, a constant that helps describe how electric fields behave in a vacuum.
