Compound PendulumHardQuestion 31178
Question
Reversible pendulum is used to measure g accurately because it has two pivots where:
- AT is maximum
- BT is minimum and same from both pivotsCorrect
- CAmplitude is constant
- DDamping is zero
Correct answer
T is minimum and same from both pivots
Explanation
Kater's reversible pendulum: adjusted so T is equal from both pivot points, which corresponds to the equivalent simple pendulum length L = distance between pivots. This gives accurate g measurement.
