The fundamental frequecy of a stationary wave formed in a stretched wire is `n= (1)/(2l) sqrt((1)/(m)) ` where `l` is length of the vibrating wire 'T' is the tension in the wire and 'm' is its mas per unit length . If the percentage error in measurement of l T and m are a% ,b% and c% respectively then find the maximum error in measuring n.

Diameter =x+ly
Here x is the M.S.R in mm l is the least count in mm and y is the vernier coincinding division Substance the given values and estimate x and y
In case of zero error,
Diameter =x+ l(y-z) where z is the V.S.D for positive zero error . (correction is negative)
