Question

If the length of the simple pendulum increases, its time period decreases.

• A. True
• B. False

Answer 1

The correct option is B False

1. Time period of simple pendulum is given as:

$$\begin{gathered} TimePeriod,T=2\pi \sqrt{\frac{l}{g}} \\ \Rightarrow T\propto \sqrt{l}\left[l=effectivelengthofpendulum\right] \end{gathered}$$

g is acceleration due to gravity.

2. Time Period is directly proportional to the square root of effective length.

Hence, the statement is false.
