A system consists of a small metallic sphere (diameter 10 cm and mass 16 kg) attached to a spring (k = 28 N/cm) and submerged in a fluid with a viscosity of 0.985 Pa.s. You need to let the system in resonance and with an oscillation amplitude of 10 cm. (a) What should be the magnitude of the external oscillating force? (b) If the system is not in resonance, what is the quality factor?
