Question

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

• A. straight line
• B. hyperbola
• C. parabola
• D. none of these

Answer 1

The correct option is C parabola

$T=2\pi \sqrt{\frac{L}{g}}$
$L=\frac{g}{4{\pi }^2}{T}^2$
$L\text{v/s}T$ will be parabola.
Final answer: (b)
