A) 8 sec
B) 56 sec
C) 224 sec
D) 0.36 sec
Correct Answer: B
Solution :
Since time period \[T=2\pi \sqrt{\frac{l}{g}}\] for one week the clock will slow down \[\frac{\Delta T}{T}=\frac{1}{2}\,\frac{\Delta l}{l}\,=\frac{1}{2}\,\alpha \Delta \theta \] For one week the clock will slow down \[1\times 7\times 24\times 60\,\times 60\,\times \,\frac{1}{2}\,\,\alpha \Delta \theta \] second.You need to login to perform this action.
