Electric Field of a Finite Line Charge

Question

A finite line of charge with length $$2L$$ and uniform linear charge density $$\lambda$$ is positioned on the x-axis from $$x = -L$$ to $$x = L$$. What is the magnitude of the electric field at point P, located at coordinates $$(0, d)$$ where $$d > 0$$?

Accepted Answer

$$(2k\lambda L)/(d\sqrt{L^2 + d^2})$$

Answer

$$(k\lambda/d)	an^{-1}(L/d)$$

Answer

$$(2k\lambda/d)\sin^{-1}(L/\sqrt{L^2 + d^2})$$

Answer

$$(2k\lambda/d)	an^{-1}(L/d)$$
