The time period of a simple pendulum is directly proportional to the square root of the length of the pendulum.
The periodic time of a simple pendulum is proportional to
In the experiment on simple pendulum, it is found that the time period of oscillation is directly proportional to its effective length. What conclusion do you draw about the shape of the curve obtained from the graph?
In the experiment to study the variation in square of time period of simple pendulum with its length:
