Assertion :Simple harmonic motion is not a uniform motion
Reason : It is the projection of uniform circle motion

Options

A. If both assertion and reason are true and the reasopn is a true explanation of the assertion
B. If both assertion and reason are true and but the reason is not the correct explanation of assertion
C. If the assertion is true but reason is false
D. If both the assertion and reason are false

Answer

B

Explanation

In simple harmonic motion
`v = omega sqrt((a^(2) - y^(2))`
As` y` changes, velocity `v` will also change so, harmonic motion is not a uniform motion
Simple harmonic motion may be defined as the projection of uniform circle motion along one of the diameters of the circle .
