Question

20. Is time period versus length graph for a simple
pendulum a straight line? Give reason for your answer.​

Answer 1

Correct option is

D

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 or a straight line
