Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

[This is not a homework, I post this for my own calculations]

Let's say that there are two different charged copper cubes with the same mass.

Mass = 2 kg

Q(1) = +10 C

Q(2) = -4 C

If the distance between them is 10 m, then how can I calculate the remaining time for the distance to be 5 m or 0 m?

I see that cubes' acceleration changes over time when I use Coloumb' law and F=m*a.

I only want to know what (t) is equal and velocity if possible.

Thanks for help.
