A) 80 kg weight
B) 240 kg weight
C) 200 kg weight
D) 160 kg weight
Correct Answer: D
Solution :
Breaking force = Breaking stress \[\times \]area of cross-section of wire \[\therefore \]Breaking force \[\propto {{r}^{2}}\] (breaking distance is constant) If radius becomes doubled, then breaking force will become 4 times ie, \[40\times 4=160\text{ }kg-wt.\].You need to login to perform this action.
