Question 1

Three Lithium nuclei (each with charge q=+3e and mass m=6.941 u) sit on the x-axis.
They are at x₁ = -1.00 mm, x₂ = 0.00 mm, and x₃ = +1.00 mm.
The middle one is held in place and the other two are released from rest.

How fast are the two released nuclei moving when they are far away? (don't forget to convert mass to kg)
