To break a wire of one-meter length, minimum 40 kg wt. is required. Then the wire of the same material of double radius and 6 m length will require breaking weight
Text Solution
Verified by ExpertsThe correct answer is:
D
Breaking force = Breaking stress × Area of cross section of wire
∴ ∴ Breaking force ∝ ∝ r 2 (Breaking distance is constant
If radius becomes doubled then breaking force will become 4 times i.e. 40 × 4 = 160 kg wt
