Challenge Problems

Push your limits with challenges.

Question 1

Two infinite wires are placed parallel to each other, one positively charged and one negatively charged with the same linear charge density. Calculate the electric field at a point midway between them.

πŸ’‘ Hint: Consider the contributions from both the positive and negative charges.

Question 2

Derive the electric field for a cylindrical wire with varying linear charge density and explain how that calculation differs from uniform charge density.

πŸ’‘ Hint: Think about how you would set up your Gaussian surface for this case.
