The weight required to stretch the spring 12.5 cm is 7.5 N (Option A)

<h3>Data obtained from the question</h3>

<h3>How to determine the new weight </h3>

The new weight required to stretch the spring can be obtained as follow:

W₁ / L₁ = W₂ / L₂

3 / 5 = W₂ / 12.5

Cross multiply

W₂ × 5 = 3 × 12.5

Divide both sides by 5

W₂ = (3 × 12.5) / 5

W₂ = 7.5 N
