In Melde's experiment it was found that the string vibrated in 3 loops when 8gm were placed in a pan. What mass must be placed in the pan to make the string vibrate in 5 loops? (Neglect the mass of the string an the pan).

Verified by Experts

`N=p/(2l) sqrt(T/m), Tp^2=4l^2 mN^2 ="a constant"`
`T_1p_1^2=T_2p_2^2, 8 xx 3^2=T_2 xx 5^2`
`T_2=(8 xx9 )/(25)=2.88gm.wt`.
