Question

A simple pendulum is taken from the equator to the pole. lts period

• A. decreases
• B. increases
• C. remains the same
• D. decreases and then increases

Answer 1

Answer: (A)

decreases

Answer 2

Time period ofpendulff is given by $\, \, \, \, \, \, \, \, T=2\pi \sqrt{\frac{l}{g}} \, or \, T ? \frac{1}{\sqrt g}$
If simple pendulum is taken from the equator to the pole, acceleration due to gravity increases.
Hence, time period of penduium decreases.
