A transverse periodic wave on a string with a linear mass density of 0.200 kg/m is described by the following equation `y=0.05 sin (420t-21.0 x)`
where x and y are in metres and t is in seconds.The tension in the string is equal to :

Options

A. 32 N
B. 42 N
C. 66 N
D. 80 N

Explanation

To find the tension in the string described by the wave equation \( y = 0.05 \sin(420t - 21.0x) \), we can follow these steps:

### Step 1: Identify the parameters from the wave equation
The given wave equation is in the form:
\[ y = A \sin(\omega t - kx) \]
where:
