A) 1000 N
B) 500 N
C) 250 N
D) 100 N
Correct Answer: C
Solution :
[c] \[\frac{\Delta \ell }{\ell }=\frac{\pi \times 0.5}{\pi \times 40}=\frac{1}{800}\] \[T=Y\frac{\Delta \ell }{\ell }\times A\] \[=200\times {{10}^{9}}\times \frac{1}{800}\times 1\times {{10}^{-6}}=250N\]You need to login to perform this action.
