Two similar sonometer wires given fundamental frequencies of 500 Hz . These have same tensions. By what amount the tension be increased in one wire so that the two wires produce 5 beats 
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
To produce 5 beats/sec. Frequency of one wire should be increase up to 505 
. i.e. increment of 1% in basic frequency.
or 
⇒ ⇒ 
⇒ ⇒ percentage change in Tension =
