Three identical 6.67-kg masses hang at rest from three identical springs, numbered as in the figure. Each spring has an unstretc
hed length of 0.23 m and a spring constant of 8.13 kN/m. How long, L , is spring 2?
[Hint: Draw some FBDs and apply Newton's second law. Remember to account for both the spring's stretch and its unstretched length.]

Answer:
the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
Explanation:
As we know that the gravitational force on electron at y = 0 is counter-balanced by the weight of the electron
So we have
here we have
also we know that
so we will have
so the bunch of 23 electrons must be placed on y axis at coordinate y = - 24.35 m.
