Spherical proteins of an unknown radius have a density of 5.80 x 103 kg/m3 and are suspended in blood which has a viscosity 3.5 times that of water. The mixture is placed in a centrifuge of radius 10.1 cm which spins at 9000 rpm. If the proteins have a terminal velocity of 3.70 x10-6 m/s, what is their radius? Express your answer to two decimal places in units of nanometers (1x10-9m), but do not include units in your answer.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
