Q. A normal human eye can see an object making an angle of $1. 8^{\circ}$ at the eye. What is the approximate height of object which can be seen by an eye placed at a distance of $1 m$ from the object?

$π c m$

$2 π c m$

$4 π c m$

$3 π c m$

$\frac{h}{1} = θ$
$\frac{h}{1} = 1.8 \times \frac{π}{180} m$
$h = \frac{1.8 \times π \times 100}{180}$
$h = π c m$
