Spring Force = $F_s$

Charge Force = $F$

If the system is balanced Based on Newton's Law On the horizontal line Is it $2F_s = F$ Or $F_s = F$ ?

Hint: Try drawing a free-body diagram. The horizontal force on the mass is spring force and charge(if the mass has charged). The direction of restoring force is in such a direction to restore the initial state of spring and the direction of coulomb force depends on the sign of charge.

  • $\begingroup$ The charge pushes each other, so there 2 springs, so wouldnt it be 2Fs + F = 0? $\endgroup$ – Lifeforbetter Nov 22 at 12:13
  • $\begingroup$ The spring force is the contact force and so it can only apply a force to a mass which is attached to it. $\endgroup$ – Young Kindaichi Nov 22 at 12:15
  • $\begingroup$ So the on side of mass theres 1 spring force and 1 F ? $\endgroup$ – Lifeforbetter Nov 22 at 12:31
  • $\begingroup$ Finding F, is F=1/(4pi.miu.) . Q^2/r^2 right? So, the F is on left mass is F=1/(4pi.miu.) . Q^2/r^2, and on right side also? $\endgroup$ – Lifeforbetter Nov 22 at 12:32
  • $\begingroup$ I'm not quite understanding what are you saying. But the restoring force should be equal to coulomb force in equilibrium conditon. $\endgroup$ – Young Kindaichi Nov 22 at 15:21
