Using a simple pendulum, plot it's L-T2 graph and use it to find the effective length of second's

APAPRATUS SUPPLIED WITH THIS EXPERIMENT

1. RETORT STAND WITH CLAMP
2. METALLIC BOB
3. STOP CLOCK
4. METER SCALE
5. VERNIER CALLIPERS
6. RUBBER CORK                                                                                        : an ideal simple pendulum experiment elaborates the motion of a simple pendulum is harmonic motion. The motion of the vibratory body from one extreme position to another extreme and back to 1st extreme position constitute one vibration time taken to complete this vibration is called time period.  Then time period can be calculate using their formulas.
