Tuning fork A when sounded with a tuning...

Tuning fork A when sounded with a tuning for B of frequency 480 Hz gives 5 beats per second. When the prongs of A are loaded with wax, it gives 3 beats per second. The original frequency of A is

A

475Hz

B

485 Hz

C

483 Hz

D

477 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
Frequency of Tuning fork A may be 475 Hz or 485 Hz, when tuning for A is waxed then frequency of A decreases so original frequency of A is 485 Hz.
