The well$-$known virus has a spherical shape with a number of spikes on the surface. The diameter of the sphere is $100$ nm and the spikes are $9$ nm long.Assume the virus as a sphere filled with water and only six spikes as long slender bars of $139$ kDa $($that is $139000$ u and u$=1\mathrm{.}6610-27$ kg$),$ mounted on the surface with equal distances to their respective neighbors $($all perpendicular to the next one$).$ Let the virus rotate around an axis collinear with an arbitrary pair of spikes $($see figure for illustration$).$ How much energy is required to let the virus do one full rotation within $10$ ms$?$ What is the angular momentum
