Question

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

Answer 1

Answer:

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.

Answer 2

Answer:

no

Explanation:

time period for an pendulum can be formulated by square root of l\g , so now the g is constant ,and thus t is directly propotional to√l

so the graph will be a increasing graph ,which is not straight ,but a kind of parabola , cos t² is propotional to l , as the value of l increase a bit ,then the value of t will increase more , as it is propotional by square ,hence it will not be straight, hope it helped you
