Question

A transverse wave propagating on the string can be described by the equation y = 2sin (10x + 300t), where x and y are in metres and t in second. If the vibrating string has linear density of 0.6 * 10-3 g/cm, then the tension in the string is
A)5.4N B)0.054 C)54N D)0.0054N

Answer 1

Hi there,

Given equation:

Y = 2sin (10x +300t)

A = 2

w = 10 rad

k = 1

now,

V = W/K

= 10/1

10 m/s.

Again,

$v = \sqrt{t} \div \: u$
T = uv^2

= 0.6* 10^-3 * 100

= 0.054 N.

Hence,Option B is correct.
