A body slides down a frictionless track which ends in a circular loop of diameter $D$, then the minimum height $h$ of the body in term of $D$ so that it may just complete the loop, is
A body slides down a frictionless track which ends in a circular loop of diameter $D$, then the minimum height $h$ of the body in term of $D$ so that it may just complete the loop, is
$h = \frac{{5D}}{2}$
$h = \frac{{5D}}{4}$
$h = \frac{{3D}}{4}$
$h = \frac{D}{4}$
A body slides down a frictionless track which ends in a circular loop of diameter $D$, then the minimum height $h$ of the body in term of $D$ so that it may just complete the loop, is
$h = \frac{5}{2}R = \frac{5}{2}\left( {\frac{D}{2}} \right) = \frac{{5D}}{4}$
