Question

Let the fundamental frequency is 45 Hz and the length of the wire is 87.5 cm. If the linear density of the wire

is 4.0 × 102 kg/m. Find the tension in the string.

Answer 1

ans:2.53*10^8N

Explanation

f =1/2L√T/μ  -this is the equation for fundumental frequency

from this we can frame an equation for tension in terms of other terms by rearranging the terms of the above equation

T=4μf²L²

hence after solving the numericals you will get the answer
