force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

what is the actual question though?
