PhysicsMediummultiple choice

Two cylinders are identical except B is hollow. Identical forces pull their right ends while their left ends are fixed.

Answer:

B, C

Solution:

$A_{B} < A_{A}$ .

$Δ L = \frac{F L}{A Y}$ .

$U = \frac{F ^{2} L}{2 A Y}$ .

B therefore elongates more and stores more energy.
