Question

A STRING OF LENGTH 8M FIXED AT BOTH ENDS HAS A TENSION OF 49N AND A MASS OF 200gm .FIND THE VELOCITY OF TRANSVERSE WAVE ON THE RING ?

Answer 1

Answer:

Explanation:Here, Length, L =10m

Mass, M =5g×10

−3

kg

Tension, T =80 N

Mass per unit length of the wire is

μ=

L

M

=

10m

5×10

−3

kg

=5×10

−4

kgm

−1

Speed of the transverse wave on the wire is

ν=

μ

T

=

5×10
