With what minimum speed $v$ must a small ball should be pushed inside a smooth vertical tube from a height $h$ so that it may reach the top of the tube? The radius of the tube is $R$ .

Options:

Answer:

Solution:

To reach at highest point of tube.

Final velocity , $v = 0$

$∴ \frac{1}{2} {m v}^{2} + m g h = m g (2 R)$

$\Rightarrow v = \sqrt{2 g (2 R - h)}$
