Question

The following table gives the relation (obtained experimentally) between the time-period and the effective length of a pendulum. Illustrate the result by a broken line graph.

Time-period (in sec)	0.6	0.8	1.2	1.4	1.6	2.0
Effective length (in cm)	10	15	235	50	70	90

Answer 1

Here is the broken line graph representing the relationship between time-period and effective length of a pendulum.

The graph shows that as the time-period increases, the effective length also increases.

This visually supports the principle that the length of a pendulum is directly related to the square of its time-period.
