اگر ایک سادہ لاکٹ کی لمبائی چار بار کی گئی ہے ، تو اس کا وقت کی مدت ______ ہوجائے گی؟
- A. One fourth
- B. Double
- C. Half
- D. None of these
Correct answer
Double
Explanation
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 .
