Homework Statement
Hooke’s law describes a certain light spring of
unstretched length 35.0 cm. When one end is attached
to the top of a doorframe and a 7.50-kg object is hung
from the other end, the length of the spring is 41.5 cm.
(a) Find its spring constant. (b) The load and the spring
are taken down. Two people pull in opposite directions
on the ends of the spring, each with a force of 190 N.
Find the length of the spring in this situation.
I am having a small problem on (b)

No
The Attempt at a Solution
Since the question says "Two people pull in opposite directions on the ends of the spring, each with a force of 190 N.", shouldn't the resultant force be 190N x 2 instead of just 190N (the answer)?
