![!
A string of linear mass density has one end attached to a vibrating
blade, of constant frequency folade, and the other passing over a pulley. A
sphere of mass 2 kg and radius R hangs as the string vibrates in its
second harmonic, as shown in Fig (a). When the sphere is completely
submerged in water (pw=10³ kg/m³), the string vibrates in its fifth
harmonic, as shown in Fig. (b).
g=9.8 m/s2
Question 1: Let T₁ denote the string tension when the sphere hangs in air, and let T₂ denote the
tension when the sphere hangs completely submerged in water. The ratio T₁/T₂ is
