A steel wire of length 64 cm weighs 5 g....

A steel wire of length 64 cm weighs 5 g. If it is stretched by a force of 8 N, what would be the speed of a transverse wave passing on it ?

Text Solution

Verified by Experts

The correct Answer is:
32 m/s
`v = sqrt((I)/(mu)) = sqrt((l)/(m))`
`= sqrt((8 xx 0.64))/(5 xx 10^(-3))` = 32 m/s
