A string of density 
and area of cross-section 
is stretched under a tension of 20 N. when it is plucked at the mid-point, the speed of the transverse waves on the wire is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Given, 
,
Mass per unit length of the wire, 
when a string is plucked at the mid-point, it vibrates with fundamental frequency.
Fundamental frequency of the stretched string is:
Speed of transverse wave, 
or
