A 25.0 Kg box is being pushed by a man horizontally. If the man applies a force of 200.0 N to keep the box moving at a constant velocity, what is the force of friction on the box? (b)
What is the μ\muμ k on the box? (Show your work)

(c)
What was the net force on the box

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

well clustered together.
