AP EAPCET 2024 - 20th May Evening Shift | Circular Motion Question 3 | Physics

A small disc is on the top of a smooth hemisphere of radius $R$. The smallest horizontal velocity $v$ that should be imparted to the disc, so that disc leaves the hemisphere surface without sliding down is ( there is no friction )

$v=\sqrt{g^2 R}$

$v=\sqrt{2 g R} 4$

$v=\sqrt{g R}$

$v=\sqrt{\frac{g}{R}}$
