Group polarization is most likely to occur in a group in which

individuals share a similar opinion. When pressured to conform, people may do the opposite of what is expected in order to increase their sense of: personal control.   i might be wrong tho

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
