Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity.
Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Options

A. If both Assertion and Reason are correct and Reason is the correct explanation of assertion.
B. If both Assertion and Reason are correct but Reason in not the correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If Assertion is false but Reason is true.

Answer

D

Explanation

`a=(v_(f)-v_(i))/(Delta t) = (dv)/(dt)` i.e., direction of acceleration is same as that of change in velocity vector, or in the direction of `Delta v`.
