Question

The graph of time period (T) of simple pendulum versus its length (l) is

Answer 1

The time period of a simple pendulum is given by:

T=2π√L/g

That means,

⇒T∝√L

⇒T²∝L

Therefore, the graph that should satisfy should be option (d) as it will be a parabola which is increasing towards L.

Hope you got it all!
