APFIVE Electric Field of a Finite Line Charge
A finite line charge of length 2L and uniform linear charge density $$\lambda$$ lies along the x-axis from $$x = -L$$ to $$x = L$$. What is the electric field at point P located at $$(0, d)$$ where $$d > 0$$?
A
$$(2k\lambda/d)\tan^{-1}(L/d)$$
B
$$(2k\lambda L)/(d\sqrt{L^2 + d^2})$$
C
$$(2k\lambda/d)\sin^{-1}(L/\sqrt{L^2 + d^2})$$
D
$$(k\lambda/d)\tan^{-1}(L/d)$$
