To find the coefficient of viscosity of the medium, we can use the formula for the drag force acting on a sphere moving through a viscous medium: \[ F = 6 \pi \mu r v \] Where: - \( F \) is the drag force (in Newtons), - \( \mu \) is the coefficient of viscosity (in poise), - \( r \) is the radius of the sphere (in centimeters), ...
