Question

A group of equally charged particles are cooled and then sent through a uniform electric field, accelerating them equally. Does this mean each particle now has more uncertainty in its position? yes or no. explain

Answer 1

YES,

the equally charged particles are cooled and then sent through a uniform electric field

and

accelerating them equally,

so using this concept or case the charged particles are moved through the a uniform electric field so they do have same velocity

finally there is no change in the velocity, but the charged particles are in motion

then the each particle now has more uncertainty in its position when accelerating

if a particle in motion means unable to find the poisition this leads to more uncertainty in its position.
