Question

Assertion : The accelerated motion of an object may be due to change in magnitude of velocity or direction of velocity or both.
Reason : Acceleration can be produed only by change in the magnitude of the velocity.
A. If both assertion and reason are trure and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanations of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason is false

Answer 1

Correct Answer - (c )
Change in the direction of the velocity also produces acceleration as in the case of circular motion. The change in the magnitude or direction of the velocity or both can produce acceleration.
