When the pendulum completes \(10\) oscillations, the time is noted
Hold the bob gently and move it to one side, to set it in motion
Make the bob of the pendulum to be at rest in its mean position
The bob is now released from its displaced position
Fix the string to the bob of the pendulum in a stand
Take a string of \(1\) metre length
The time period for one complete oscillation is calculated by dividing the \(10\) oscillations by \(10\)
