1.	The bob of a pendulum at rest is given a sharp hit to impart a horizontal velocity u. If l is the length of the pendulum, find the tension in the string when θ=90∘ from the vertical. Given: u=√3gl
Answer» The bob of a pendulum at rest is given a sharp hit to impart a horizontal velocity $u$ . If $l$ is the length of the pendulum, find the tension in the string when $θ = 90^{\circ}$ from the vertical. Given: $u = \sqrt{3 g l}$

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?
