When a massless spring is pulled by 5N on both sides the tension in the spring is 5N (proved by considering COM at rest and breaking the spring into two springs of 2k each)...what if the forces applied were 5N at one end and 7N at the other end?What would be the resultant tension in the spring?

    $\begingroup$ It's not possible to pull on the two ends of a massless spring with different tensions. $\endgroup$ – Chet Miller Aug 20 at 19:52
