In an experiment with sonometer when a mass of

180 \, \mathrm{g}

is attached to the string, it vibrates with fundamental frequency of

30 \, \mathrm{Hz}

. When a mass

m

is attached, the string vibrates with fundamental frequency of

50 \, \mathrm{Hz}

. The value of

m

is ________

\text{g}.

View answer and explanation

Correct option: A

500

Option A (500) is correct because the frequency of a vibrating string is proportional to the square root of the tension, which is proportional to the mass attached.
