Answer 2

Answer:

248 N

Explanation:

Given , M= 3.5 × 10^-2 Kg

m=4.0 × 10^-2 Kg m^-1

Length of string , L= M/m

= 3.5 × 10^-2/4.0×10^-2

=0.875 m

(a)Fundamental Frequency, n=v/2L

=>Speed, v = n(2L)=45×2×(0.875)

=78.75ms^-1=79ms^-1

(b)Tension T is given by v= root T/m

=> T = v^2 m=(78.75)^2×4.0×10^-2

=248 N
