In Young's double slit experiment, the distance between slits and the screen is $\displaystyle 1.0$ m and monochromatic light of $\displaystyle 600$ nm is being used. A person standing near the slits is looking at the fringe pattern. When the separation between the slits is varied, the interference pattern disappears for a particular distance $\displaystyle d_0$ between the slits. If the angular resolution of the eye is $\displaystyle \frac{1^{\circ}}{60}$, the value of $\displaystyle d_0$ is close to :

(2)
$\displaystyle 2$ mm
