Question

The minimum height of the obstacle so that the sphere can stay in equilibrium is (R is radius of the sphere)

$\frac{R}{1 + \sin θ}$
$\frac{R}{1 + \cos θ}$
$R (1 - \sin θ)$
$R (1 - \cos θ)$

The correct answer is: $R left parenthesis 1 minus cos invisible function application theta right parenthesis$

$text If end text theta text is angle between direction of end text mg text and normal to incline passing through centre of sphere, end text cos invisible function application theta equals open parentheses fraction numerator R minus h over denominator R end fraction close parentheses$

A uniform circular disc has radius R and mass m. A particle also of mass m is fixed at a point A on the edge of the disc as shown in the figure. The disc can rotate freely about a fixed horizontal chord P Q that is at a distance R/4 from the center C of the disc. The line AC is perpendicular of P Q. Initially, the disc is held vertical with the point A at its highest position. It is then allowed to fall so that it starts rotating about P Q. Find the linear speed of the particle as it reaches its lowest position.
