A small mass 'm' is suspended at the end of a wire having (negligible mass) length 'L' and cross-sectional area 'A'. The frequency of oscillation for the S.H.M. along the vertical line is ( Y = Young's modulus of the wire)
Options
- A1 2 ( YA mL )^ 1 2
- B2 YA mL
- CYA 2 mI
- D2 ( YA mL )^ 1 2
Correct answer
A. 1 2 ( YA mL )^ 1 2
Step-by-step solution
If x is the extension of the wire then P= ( Y A L ) x F=k x where k= Y A L frequency of oscillation is given by f= 1 2 k m = 1 2 Y A mL
