Question

Given below are two statements.

Statement $\left(1\right)$ : A second's pendulum has a time period of $1\text{second}$.

Statement $\left(2\right)$ : 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.

• A. Both statement $1$ and statement $2$ are false.
• B. Statement $1$ is true, but statement $2$ is false.
• C. Statement $1$ is false, but statement $2$ is true.
• D. Both statement $1$ and statement $2$ are true.

Answer 1

The correct option is C Statement $1$ is false, but statement $2$ is true.

Second pendulum has a time period of $2\text{second}$, so, statement $1$ is false.

But to move from one extreme position to other, it takes $1\text{second}$, so, statement $2$ is true.
