In melde's experiment, when the tension decreases by 0.009 kg-wt, the number of loops changes from 4 to 5 . The initial tension is
Options
- A0.036 kg-wt.
- B0 009 ~kg -wt.
- C0 018 kg-wt.
- D0.025 kg-wt.
Correct answer
D. 0.025 kg-wt.
Step-by-step solution
For Melde's experiment. TP ²= constant where T is the tension and P is the number of loops. array l T ₁ P ₁ ²= T ₂ P ₂ ² T ₁(4)²= ( T ₁-0.009 )(5)² 9 ~T ₁=0.009 25 T ₁=0.025 ~kg - wt array
