Springs in series affecting the uncertainty

[edwan001]

Homework Statement

The question is: 'State how adding three springs in series when setting up the masses experiment to measure the spring constant of a spring will affect the absolute uncertainty and the percentage uncertainty for the extension and the value of the spring constant'. Thank you!

Relevant Equations

F = Ke
F = 1/2Ke^2

No idea on this one - I know that the spring constant will divide by 3 but am unsure how this will affect the % and the absolute uncertainties. Completely stuck on the extension...

Hello Edwan, !

Not the way PF works ! You have to make an inroad somehow by posting an attempt at solution.
Just 'dunno' isn't good enough !
There's something wrong with your equations, too. From F = F, I conclude e = 2.

To get you going: your knowledge "that the spring constant will divide by 3" in combination with $F = K e$ where (F = , K = , e =...) leads to ...
