1.	A spherically symmetric gravitational system of particles has a mass density ρ={ρ0 for r≤R0 for r>Rwhere ρ0 is a constant. A test mass can undergo circular motion under the influence of the gravitational field of particles. Its speed V as a function of distance r(0<r<∞) from the centre of the system is represented by
Answer» A spherically symmetric gravitational system of particles has a mass density $ρ = {\begin{matrix} ρ_{0} for r \leq R 0 for r > R \end{matrix}$ where $ρ_{0}$ is a constant. A test mass can undergo circular motion under the influence of the gravitational field of particles. Its speed $V$ as a function of distance $r (0 < r < \infty)$ from the centre of the system is represented by

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?
