The heisenberg uncertainty principle is best applied to what type of objects

Quantum objects.

Explanation: The Heisenberg uncertainty principle is best applied to quantum objects, where the principal says that we can not fully determine the position and moment of a particle, there is a minimal error in the determinations that fulfill the uncertainty principle.

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
