A smooth wire is bent into a vertical circle of radius a. A bead P can slide smoothly on the wire. the circle is rotated about diameter AB as axis with a speed ω as shown in figure. The bead P is at rest with respect to the circular ring in the position shown. Then ω2 is equal to-
- 2g /a
- 2g / (a \(\sqrt{3}\))
- \(2 \sqrt{3} \mathrm{~g} / \mathrm{a}\)
- 2a / (g \(\sqrt{3}\))
Answer
(B) 2g / (a 3 )
