A simple pendulum consists of a pivot point at the top, a thin string of length L extending downwards at a small angle from a vertical dashed line. A circular bob of mass m is at the end of the string. A curved double-headed arrow indicates the path of oscillation.
A simple pendulum oscillating at a small angle.
A student is performing an experiment with a simple pendulum to determine how its properties affect the time it takes to complete one full oscillation. In the first trial, a bob of mass \( m \) is attached to a string of length \( L \), and the period is measured to be \( T \). In a second trial, the student replaces the string with one of length \( 4L \) while keeping the same bob and the same small initial launch angle. Which of the following correctly describes the change in the period of the pendulum for the second trial?
