JEE MAIN - Physics (2021 - 26th February Evening Shift - No. 19)
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 given below :
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 given below :
Both Statement I and Statement II are false
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Statement I is true but Statement II is false
Explanation
As we know time period of second’s penduklum is 2 sec, so statement (1) is incorrect.
Time taken by particle performing SHM between two extreme position is half of the time period.
Here, T = 2 sec.
So, time = 2/2 = 1 sec
Time taken by particle performing SHM between two extreme position is half of the time period.
Here, T = 2 sec.
So, time = 2/2 = 1 sec
