Solution

## The correct option is B π4+tan−1(0.5) with x− axis Given, θ=45∘ Let α be the angle making by net electric field at point P with OP. So, from the formula, tanα=tanθ2 ⇒tanα=tan45∘2⇒tanα=0.5 ⇒α=tan−1(0.5) Thus, the angle which Enet makes with x− axis is 45∘+tan−1(0.5)=π4+tan−1(0.5) So, (b) is correct option.
