Question

A length L of flexible tape is tightly wound. It is then allowed to unwind as it rolls down a steep incline that makes an angle  with the horizontal, the upper end of the tape being tacked down. Then, the tape unwinds completely in time equal to –

$\sqrt{2 L / g \sin θ}$
$\sqrt{3 L / g \sin θ}$
$\sqrt{L / g \sin θ}$
None of these

The correct answer is: $square root of 3 L divided by g sin invisible function application theta end root$
