Question 6

An elastic cord in a luggage restraint is stretched without exceeding its limit of proportionality. The force applied to the cord is FFF, its spring constant is k k\,k and its extension is eee.

Which equation should be used to calculate the extension of the cord?

[1]
A

e=F×ke = F \times ke=F×k

B

e=F÷ke = F \div ke=F÷k

C

e=F÷ke = \sqrt{F \div k}e=F÷k​

D

e=k÷Fe = k \div Fe=k÷F
