For a simple pendulum, the graph between\[{{T}^{2}}\]L is
A) a straight line passing through the origin
B) parabola
C) circle
D) ellipse
E) hyperbola
Correct Answer:
A
Solution :
\[T=2\pi \sqrt{\frac{L}{g}}\] Or \[T\propto \sqrt{L}\]or\[{{T}^{2}}\propto L\] It is linear relation between\[{{T}^{2}}\]and\[l\]hence the graph between\[{{T}^{2}}\]and L is a straight line passing through the origin.
