A) \[{{T}_{1}}={{T}_{2}}\]
B) \[{{T}_{1}}>{{T}_{2}}\]
C) \[{{T}_{1}}<{{T}_{2}}\]
D) None of these
Correct Answer: C
Solution :
[c] Rate of coiling\[=\frac{-d\theta }{dt}\propto \left( \frac{{{\theta }_{1}}+{{\theta }_{2}}}{2}-{{\theta }_{0}} \right)\] In second case average temperature will be less hence rate of coiling will be less. Therefore time taken will be more than 4 minutes.You need to login to perform this action.
