A simple spring is used to measure force. The spring is considered to be linear, so that F = kx, where F is the force in Newtons, k is the spring constant in newtons per centimeter, and x is the displacement in cm. If x = 12.5 + 1.25 cm and k = 700 + 18 N/cm, calculate the best estimate of the uncertainty of the measured force in relative terms (i.e., in terms of % of the measured force).

Question
A simple spring is used to measure force. The spring is
considered to be linear, so that F = kx, where F is the force in
Newtons, k is the spring constant in newtons per centimeter,
and x is the displacement in cm. If x = 12.5 + 1.25 cm and k =
700 + 18 N/cm, calculate the best estimate of the uncertainty
of the measured force in relative terms (i.e., in terms of % of
the measured force).
