A string wave equation is given y = 0.002 `sin(300t-15x)` and mass density is `(mu=(0.1kg)/(m))`. Then find the tension in the string

A

30 N

B

20 N

C

40 N

D

45 N

Text Solution

Verified by Experts

The correct Answer is:
C
In string were speed is `V=sqrt((T)/(mu))`
`T=mV^(2)`
`T=1.20xx20=40N`
`V=(omega)/(k)=(300)/(15)=20M//S`
