Question:
Given below are two statements :
Statement (I) :- A second's pendulum has a time period of 1 second.
Statement (II) :- It takes precisely one second to move between the two extreme positions.
In the light of the above statements, choose the correct answer from the options give below.
Correct Option: , 3
Solution:
(3)
As we know time period of second's penduklum is 2 sec, so statement (1) is incorrect.
Time taken between two extreme points in second's pendulum is $1 \mathrm{sec}$.
Above statement is correct because time taken by particle performing SHM between two
extreme position is $\mathrm{T} / 2$.
Here, $T=2 \mathrm{sec} .$
So, time $=2 / 2=1 \mathrm{sec}$
