Given below are two statements: Statement I : A second's pendulum...

Given below are two statements:
Statement II: A second's pendulum has a time period of 11 second.

Statement IIII: 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

Options

  1. AStatement II is false but Statement IIII is true
  2. BBoth Statement II and Statement IIII are true
  3. CBoth Statement II and Statement IIII are False
  4. DStatement II is true but Statement IIII is false

Correct answer

A. Statement II is false but Statement IIII is true

Step-by-step solution

Second pendulum has a time period of 2s2s so statement 11 is false but from one extreme to other it takes only half the time period so statement 22 is true.
