Waves question

2017 · 9 Apr · Shift 1 · Q50

JEE MainPhysicsWavesMCQ+4 / −1
In an experiment to determine the period of a simple pendulum of length 1 m, it is attached to different spherical bobs of radii r1 and r2 . The two 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, ∣\left| {} \right.∣ r1 −-− r2 ∣\left| {} \right.∣ is best given by :
  1. A
    1 cm
  2. B
    0.05 cm
  3. C
    0.5 cm
  4. D
    0.01 cm
