A hollow vertical cylinder of radius r and height h has a smooth internal surface. A small particle is placed in contact with the inner side of the upper rim, at point A , and given a horizontal speed u , tangential to the rim. It leaves the lower rim at point B , vertically below A . If n is an integer then

Options:

Answer:

Solution:

Time of travel from $A$ to $B$ , $t = \frac{2 h}{g}$

$\Rightarrow 2 π r n = u t \Rightarrow 2 π r n = u \frac{2 h}{g} \Rightarrow n = \frac{u}{2 π r} \frac{2 h}{g}$
