Two wires of the same material and length but different cross-sectional areas A1 and A2 (A1 > A2) are subjected to the same tensile force. Which wire will experience a greater elongation?
The wire with cross-sectional area A1
The wire with cross-sectional area A2
Both wires will experience the same elongation
The elongation depends on the density of the material
