If two tuning forks A & B give 4 beats/sec. with each other, on loading A with wax , 2 beats/sec. are given. If frequency of A is 256 Hz, then frequency of B is-

A

250 Hz

B

252 Hz

C

260Hz

D

262Hz

Text Solution

Verified by Experts

The correct Answer is:
B
Frequency of Tunninf forks B may be 260 Hz or 252 Hz, when tunning for A is waxed then frequency of A decreases so original frequency of B is 252.
