If the length of a simple pendulum is made four times, then its Time period will become ______?
اگر ایک سادہ لاکٹ کی لمبائی چار بار کی گئی ہے ، تو اس کا وقت کی مدت ______ ہوجائے گی؟
Answer: Double
Explanation
The time period (T) of a simple pendulum is given by:
T ∝ √L
If the length (L) is made four times:
New time period T' ∝ √(4L)
T' ∝ 2√L
T' = 2T
The time period will become double.
