Solution

## The correct option is C tan−1(√2)So, here, when we take an axis inclined at angle θ to dipole axis,and if the net field from that inclined axis makes angle θ, then,tanα=tanθ2cotα=2tanθ......................(1)So, from figure,clearly,α+θ=90 therefore, θ=90−αSo, tanθ=tan(90−α) tanθ=cotα...... (using trigonometric relation).............(2)From eqns.(1) and (2),tanθ=2tanθtan2θ=2tanθ=√2θ=tan−1√2
