Question

using a simple pendulum, plot its l-t2 graph and use it to find the effective length of second's pendulum. observation , calculation , results must be written​

Answer 1

Explanation:

Observations:

• Vernier constant of vernier callipers (V.C.) = …cm.
• Zero error of vernier callipers (e) :(i)………cm, (ii)……..cm, (iii)……….cm.
• Mean zero error, (e) = ……….cm
• Mean diameter, d=d0+c=……….cm
• Mean radius of the bob, r=d/2=………….cm
• Length of , bob hook  h=……….cm
• Standard value of g-950 cm s-2.
• Least count of stop clock= ……s  
• Table Length (l) and time (T)

Calculations:  

• Here is the Mean values, For each l.
• find tp T =t/20 s and of T2 l-T2 graph.
• Plot a graph between l and T2 by taking Z along X- axis and T2 along Y-axis.
• The graph comes to be a straight line
