How would I go about doing an experiment that would demonstrate Coulomb's law? Thanks :D

Obtain 3 identical small metal spheres, each suspended by silk thread. Measure the mass of the spheres. Pass the thread from 2 of the spheres through a small loop and tie off the thread equally above the loop. Develop a system so you can raise and lower the loop along the thread between the tie...

;) What is coulomb's law? How does it work and what's the formula?

Hey I was wondering if anyone can help me on this problem below :) The velocity of a particle moving in a straight ine with uniform acceleration increases from 10m/s to 20m/s in 30m. When and where was the velocity 15m/s Thx:D
