In a two dimensional motion, a particle moves from point A (position vector →r1), to point B (position vector →r2). If the magnitudes of these vectors are r1=3 m and r2=4 m and the angles they make with the x-axis are θ1=75∘ and θ2=15∘, respectively, then the magnitude of the displacement vector (in m) is

1.	In a two dimensional motion, a particle moves from point A (position vector →r1), to point B (position vector →r2). If the magnitudes of these vectors are r1=3 m and r2=4 m and the angles they make with the x-axis are θ1=75∘ and θ2=15∘, respectively, then the magnitude of the displacement vector (in m) is
Answer» In a two dimensional motion, a particle moves from point A (position vector ${\to r}_{1}$ ), to point B (position vector ${\to r}_{2}$ ). If the magnitudes of these vectors are $r_{1} = 3 m$ and $r_{2} = 4 m$ and the angles they make with the x-axis are $θ_{1} = 75^{\circ} and θ_{2} = 15^{\circ}$ , respectively, then the magnitude of the displacement vector (in $m$ ) is

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?
