Two blocks of masses m1=m2=m are connected by a string of negligible mass which passes over a frictionless pulley fixed on the top of an inclined plane as shown in the figure. When the angle of inclination θ=30∘, the mass m1 just begins to move up the inclined plane. What is the coefficient of friction between blockm1 and the inclined plane?

1.	Two blocks of masses m1=m2=m are connected by a string of negligible mass which passes over a frictionless pulley fixed on the top of an inclined plane as shown in the figure. When the angle of inclination θ=30∘, the mass m1 just begins to move up the inclined plane. What is the coefficient of friction between blockm1 and the inclined plane?
Answer» Two blocks of masses $m_{1} = m_{2} = m$ are connected by a string of negligible mass which passes over a frictionless pulley fixed on the top of an inclined plane as shown in the figure. When the angle of inclination $θ = 30^{\circ}$ , the mass $m_{1}$ just begins to move up the inclined plane. What is the coefficient of friction between block $m_{1}$ and the inclined plane?

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?
