Question

Assertion : Simple harmonic motion is the projection of uniform circular motion on the diameter of the circle in which the later motion occurs.
Reason : Simple harmonic motion is a uniform motion.

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

Answer 1

The correct option is C If assertion is true but reason is false.

Simple harmonic motion is expressed by $v=\omega \sqrt{a^2-y^2}$. With change in displacement y, velocity v changes. Thus simple harmonic motion is not a uniform motion.
