Answer 1

Answer:

(d) Assertion (A) is false but reason(R) is true.

Explanation:

The velocity of a body is a vector quantity. And so, the Assertion (A) is false.

But, the vector quantity has both magnitude and direction. So, the reason (R) is true.

**A scalar quantity is the quantity which has only magnitude and no direction. EXAMPLE:- Speed.
