The elongation of the spring under this load is 6.5 m (Option B)

Data obtained from the question

  • Force (F) = 78 N
  • Spring constant (K) = 12 N/m
  • Elongation (e) = ?

How to determine the elongation of the spring

The elongation of the spring can be obtained as illustrated below:

F = Ke

Divide both sides by K

e = F / K

e = 78 / 12

e = 6.5 m
