Question

52. If the period of vibration of the prongs of a fork
depends upon density of the material, Young's
modulus and the length of the prongs , the
expression of time period is ( k is a constant )
1) T=(k/1) VpY
2)T=kl Vo/Y
3) T = (k/l) Vply 4) klp/​

Answer 1

Answer:

As T depends on l, ρ and YSo, T = klaρbYc ...........(i)where, k = dimensionless constantSubstituting the dimension of each quantity in Eq.(i) [M0L0T1] ...
