1.	A small ring P is threaded on a smooth wire bent in the form of a circle of radius a and center O. The wire is rotating with constant angular speed ω about a vertical diameter xy, while the ring remains at rest relative to the wire at a distance a2 from xy. Then ω2 is equal to
Answer» A small ring $P$ is threaded on a smooth wire bent in the form of a circle of radius $a$ and center $O$ . The wire is rotating with constant angular speed $ω$ about a vertical diameter $x y$ , while the ring remains at rest relative to the wire at a distance $\frac{a}{2}$ from $x y$ . Then $ω^{2}$ is equal to

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
