A) Increase
B) Decrease
C) Remain unaffected
D) Become infinite
Correct Answer: B
Solution :
Initially time period was \[T=2\pi \sqrt{\frac{l}{g}}\]. When train accelerates, the effective value of g becomes \[\sqrt{({{g}^{2}}+{{a}^{2}})}\] which is greater than g Hence, new time period, becomes less than the initial time period.You need to login to perform this action.
