Atable rests on the floor and pushes on the floor with its weight of 12 lb. with how much force (in pounds) does the floor push on the table?lb.

if we are being technical then 12 lbs of force

everything has an equal and opposite reaction

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

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
