MCQ
A simple pendulum is ta ken from the equator to the pole. Its period
  • ✓
    Decreases
  • B
    Increases
  • C
    Remains the same
  • D
    Decreases and then increases
✓

Answer

Correct option: A.
Decreases
(a) As we go from equator to pole the value of $g$ increases.Therefore time period of simple pendulum $T \frac{1}{\sqrt{g}}$ decreases. $\quad T \quad \frac{1}{\sqrt{g}}$
