For a simple pendulum the graph between length and time period will be

A

straight line q

B

curve

C

ellipse

D

parabola

Text Solution

Verified by Experts

The correct Answer is:
D
The time period of a simple pendulum is

`T=2pisqrt((l)/(g))`
Here, l is the length of the pendulum. On squaring both sides
`T^(2)=(4pi^(2)l)/(g)`
`impliesT^(2)propl`
So, the graph between time period T and length l of the pendulum is a parabola.
