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

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

Solution

In simple harmonic motion, $v = ω \sqrt{(a^{2} - y^{2})}$
as y changes, velocity v will also change. So, simple harmonic motion is not a uniform motion. Simple harmonic motion may be defined as the projection of uniform circular motion along one of the diameters of the circle.
