Question

A vibrating tuning fork is moving slowly and uniformly in a horizontal circular path of radius 8 m. The shortest distance of an observer in same plane from the tuning fork is 9 m. The distance between the tuning fork and observer at the instant when apparent frequency becomes maximum is (A) 9 m (B) 25 m (C) 15 m (D) √353 m

The apparent frequency is maximum when relative velocity of approach of tuning fork with respect to observer is maximum <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/9970e8cdcbaf8f46fbe43e93d77eabb1-.png" /> O P=√172-82=15 m

Q. A vibrating tuning fork is moving slowly and uniformly in a horizontal circular path of radius $8 m$ . The shortest distance of an observer in same plane from the tuning fork is $9 m$ . The distance between the tuning fork and observer at the instant when apparent frequency becomes maximum is

9 m

25 m

15 m

$353 m$

The apparent frequency is maximum when relative velocity of approach of tuning fork with respect to observer is maximum

$OP = 1 7^{2} - 8^{2} = 15 m$
