# In the relation $y = r\sin (\omega t + kx)$, the dimensional formula for $kx$ or $\omega t$ is same as

$r / y$

##### SOLUTION
$(\omega t + kx)$ is dimensionless because sine and cosine operations are done on dimensionless quantities.
$\therefore \omega t$ and $kx$ are both dimensionless.
Out of the given options, only $r / y$ is dimensionless.

You're just one step away
