1.	The bridge of a sonometer is slightly displaced so that the length of wire is decreased by 0.5% and tension in the wire is increased by 1%. The fundamental frequency of wire
Answer» INCREASES by `1%` decreases by `1%` increases by `1.5%` decreases by `1.5%` SOLUTION :`n prop (sqrt(T))/(l)implies(DELTAN)/(n)=(1)/(2)(DELTAT)/(T)-(Deltal)/(l)`
