**For a simple pendulum performing simple harmonic motion, the time period is plotted against its length. The curve will be **

### Options

(a) straight line

(b) circle

(c) parabola

(d) ellipse

### Correct Answer:

parabola

### Explanation:

Time period of a simple pendulum performing simple harmonic motion is given by

T = 2π √(l/g) where l is the length of the pendulum

or, T² = 4π²l/g or, T² ∝ l

Graph between T and l is a parabola.
