A frictionless track $ABCDE$ ends in a circular loop of radius $R$. A body slides down the track from point $A$ which is at a height $h = 5\, cm$. Maximum value of $R$ for the body to successfully complete the loop is ........... $\mathrm{cm}$
Condition for vertical looping $h = \frac{5}{2}r = 5cm$
$r = 2\, cm$
