A block of mass $m$ is placed at the top of a smooth wedge $A B C$ . The wedge is rotated about an axis passing through $C$ as shown in the figure. The minimum value of angular speed $ω$ such that the block does not slip on the wedge is-

Options:

Answer:

Solution:

$m ω^{2} r \cos θ = m g \sin θ$

$m ω^{2} l \cos^{2} θ = m g \sin θ$

$ω = \sqrt{\frac{g \sin θ}{l \cos^{2} θ}} = \sqrt{\frac{g \sin θ}{l}} \sec θ$
