Question

(3 Draw the
graph of T² and L
for a simple pendulum
for different values of L
Here,L is the length and T is the time period of
pendulum.
​

Answer 1

parabola

The time period of a simple pendulum is

T=2π

g

l

Here, l is the length of the pendulum.

On squaring both sides

T

2

=

g

4π

2

l

⇒T

2

∝l

So, the graph between time period T and length l of the pendulum is a parabola.
