Question

Directions: In the following questions, a statement of assertion is followed by a statement of reason.
Mark the correct choice as:
(a) If both assertion and reason are true and reason is the correct explanation of assertion.
(b) If both assertion and reason are true but reason is not the correct explanation of assertion.
(c) If assertion is true but reason is false.
(d) If assertion is false but reason is true.
Assertion: Unit of velocity and speed is same in SI system.
Reason: Speed and velocity are scalar quantities.

Answer 1

Explanation for assertion statement

1. Unit of velocity and speed are the same in the SI system.
2. Unit of velocity and speed is the same as m/s.

Explanation for reason statement

1. Velocity is a vector quantity while speed is a scalar quantity.
2. $Velocity=\frac{displacement}{time}$.
3. $Speed=\frac{dis\tan ce}{time}$.

Therefore, the assertion is true but reason is false.

Hence, option (c) is the correct answer.
