A wire can be broken by a load of 20 kg-wt. The force required to break wire of same material with twice the diameter will be

View answer and explanation

Correct option: D

80 kg-wt

Option D (80 kg-wt) is correct because the breaking force is proportional to the cross-sectional area, which is proportional to the square of the diameter.
