An engine is moving on a circular path of radius 200 m with a speed of 15 m/s. What will be the frequency observed by an observer standing at rest, at the centre of the circular path, when the engine blows a whistle of frequency 250 Hz?

A

more than 250 Hz

B

less than 250 Hz

C

equal to 250 Hz

D

500 Hz or zer

Text Solution

Verified by Experts

The correct Answer is:
C
There is no change in frequency because there is no relative motion between the source and the observer
