A small body of mass m=10 kg hangs at one end of a string of length l, the other end of which is fixed. It is given horizontal velocity u at its lowest position. The string just becomes slack, when it covers an angle 120∘ with the initial position. Find the tension in the string at the point of projection. Take g=10 m/s2

1.	A small body of mass m=10 kg hangs at one end of a string of length l, the other end of which is fixed. It is given horizontal velocity u at its lowest position. The string just becomes slack, when it covers an angle 120∘ with the initial position. Find the tension in the string at the point of projection. Take g=10 m/s2
Answer» A small body of mass $m = 10 kg$ hangs at one end of a string of length $l$ , the other end of which is fixed. It is given horizontal velocity $u$ at its lowest position. The string just becomes slack, when it covers an angle $120^{\circ}$ with the initial position. Find the tension in the string at the point of projection. Take $g = 10 {m/s}^{2}$

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?
