Assertion: In `y = A sin (omega t - kx),(omega t - kx)` is dimensionless.
Reason: Because dimension of `omega = [M^(0)L^(0)T]`.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
C
`y = Asin(omegat - kx)`
`[omegat] = [kx ] = [M^0 L^0 T^0] rarr` dimensionless
`[omega] = [T^(-1)]`
