Question

In an experiment to determine the period of a simple pendulum of length 100 cm , it is attached to different spherical bobs have uniform mass distribution. If the relative difference in the periods is found to be 5 10⁻⁴ ~s , the difference in radii |r₁-r₂ | is best given by

Correct answer: B. 10⁻³ ~m

Given, T=5 10⁻⁴ ~s We know that, array cc & T=2 l g & T l & T= 1 2 l & 5 10⁻⁴= |r₁-r₂ | 2 & |r₁-r₂ |=2 5 10⁻⁴=10⁻³ ~m array
