A wire with a circular cross-section that obeys Hooke’s law is used to support a basket, as illustrated. The Young modulus of the wire’s material is $2.5 \times 10^{11}\ \text{Pa}$. When an additional load of $34\ \text{N}$ is placed in the basket, the strain in the wire rises by $6.0 \times 10^{-5}$. What is the radius of the wire?
- A$7.2 \times 10^{-7}\ \text{m}$
- B$2.3 \times 10^{-6}\ \text{m}$
- C$8.5 \times 10^{-4}\ \text{m}$
- D$1.7 \times 10^{-3}\ \text{m}$
