Answer:
120 kg
Step-by-step explanation:
Breaking stress is the characteristic of the material. Hence, for two wires of same material having different thickness.
Minimum load = 30 kg. radius r = (2r)
F₁ / r₁² = F₂ / r₂²
==> F₁ / r² = F₂ / (2r)²
==> 30 / r² = F₂ / 4r²
==> F₂ = 120 kg.
Minimum mass required = 120 kg.
