Two infinitely long line charge of same linear charge density λ are arranged as shown in figure. The magnitude of electric field intensity at point P as shown in figure.
Answer & explanation
Correct answer: option 2
At point P
P = 2Ey
$=2 \frac{K \lambda}{R \cos \theta}\left[\cos \theta-\cos 90^{\circ}\right]$
$=\frac{2 K \lambda}{R}$.
