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:
A, B, C
Mass=5 gm
length =64 cm
`:. Mass per unit length
`=5/64 gm/cm `
`:. Tension, T=8N`
`=8xx10^5dyne`
`V=sqrt((T/m))`
`=sqrt((8x10^5xx64)/5)`
`=3200cm/s=32m/s`
