The length of the string of a simple pendulum is measured with a metre scale to be 90.0 cm.The radius of the bob plus thelength of the hook is calculated to be 2.13 cm using measurements with a slide callipers. What is the effective lengthof the pendulum? (The effective length is defined as the distance between the point of suspension and the centre of the bob.)

A

87.87 cm

B

92.1 cm

C

91.2 cm

D

90.2 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`L=90.0cm, r=2.13cm`.
`"Effective length "=90.0+2.13=92.1 cm.`
