A) T
B) \[\frac{T}{2}\]
C) \[2T\]
D) \[\frac{T}{4}\]
Correct Answer: B
Solution :
By cutting spring in four equal parts force constant (K) of each parts becomes four times \[\left( \because \,k\propto \frac{1}{l} \right)\]so by using \[T=2\pi \sqrt{\frac{m}{K}};\]time period will be half, i.e., \[T'=T/2\]You need to login to perform this action.
