Question
The length of the string of a simple pendulum is measured with a meter scale to be 63.5 cm, the radius of the bob plus the hook is measured with the help of vernier to be 1.55 cm. Select the incorrect statement : -
Options
A.Least count of meter scale is 0.1 cm
B.Least of vernier caliper is 0.01 cm
C.Effective length of pendulum is 65.1 cm.
D.Effective length of pendulum is 65.2 cm
Solution
From measurements least count meter scale is 0.1 cm and least count of vernier caliper is 0.01 cm. Effective length of simple pendulum = 63.5 + 1.55 = 65.15 = 65.2 cm
