So there is this ball held on a spring. It's radius R = 0.015m , and density ρ=7800kg/m^3.
It's oscillation period in air is 1.256 seconds and in the fluid it changes to 1.57 seconds.
Find the viscosity of the fluid considering that the drag force obeys Stokes law.
I first found the spring constant k to be k = 2.76.
But how do I find the drag force without knowing the terminal velocity? Or is there a way of solving this otherwise.
Darn I posted this in the wrong section. May someone please move it to the coursework section?
Sorry for the inconvenience
