Option 1: 6s

This option suggests that the time period of a 1 m long pendulum is approximately 6 seconds. However, this is incorrect. The time period of a pendulum is determined by the length of the pendulum and the acceleration due to gravity. The relation between the time period (T) and the length (L) of a simple pendulum is given by the formula T=2π√(L/g), where g is the acceleration due to gravity. Therefore, the time period of a 1 m long pendulum will not be 6 seconds.

Option 2: 4s

This option suggests that the time period of a 1 m long pendulum is approximately 4 seconds. However, this is incorrect. As explained above, the time period of a pendulum is determined by its length and the acceleration due to gravity. Therefore, the time period of a 1 m long pendulum will not be 4 seconds.

Option 3: 2s

This option suggests that the time period of a 1 m long pendulum is approximately 2 seconds. This is the correct answer. The time period of a simple pendulum is approximately given by the formula T=2π√(
