Question:

The variation of electric field intensity due to a thin long straight wire of uniform linear charge density '$\lambda$' with distance r from the wire is correctly represented by:

Options:

Correct Answer:

Explanation:

The correct answer is Option (2)

Electric field due to a long straight wire, $\vec E=\frac{1}{2πε_0}\frac{λ}{r}$

$⇒\vec E∝\frac{1}{r}$
