A) Increases
B) Decreases
C) Remains same
D) Increases or decreases depending on the material
Correct Answer: B
Solution :
With temperature rise frequency of tuning fork decreases. Because, the elastic properties are modified when temperature is changed also, \[{{n}_{t}}={{n}_{s}}(1-0.00011t)\] where \[{{n}_{t}}=\] frequency at \[t{}^\circ C\], \[{{n}_{s}}\]= frequency at \[0{}^\circ C\]
