What is the difference between charged object and uncharged objects?

the difference between a charged body is an body that has either a surplus or deficiency of electrons, and is negatively and positively charged respectively. And the difference between an uncharged body is that it’s  a 'neutral' body that has an equal number of protons and electrons.

Explanation:

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
