The period of vibration (T) of the prongs of a tuning fork depends upon density of the material d, Young's modulus Y and length of the prongs L. Then

The period of vibration (T) of the prongs of a tuning fork depends upo

1.	The period of vibration (T) of the prongs of a tuning fork depends upon density of the material d, Young's modulus Y and length of the prongs L. Then
Answer» `T ALPHA (sqrt(DY))/(L)` `T alpha L sqrt((d)/(Y))` `T alpha(1)/(L) sqrt((d)/(Y))` `T alpha (LD)/(sqrt(Y))` Answer :B
