Question

Assertion: A car moving due east, takes a turn and starts moving towards north without any change in its speed. There will be no change in the velocity of the car.
Reason: Velocity is a vector quantity

i)Both Assertion and Reason are true, and Reason is the correct explanation of the Assertion.
ii) Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.
iii) Assertion is true but Reason is false.
iv) Assertion is false, but Reason is true.

Answer 1

ANSWER:------->

(I) ✓✓ Both Assertion and reason are true, and reason is the correct explaination of the assertion.

because velocity is a vector quantity

and also there is no change in the velocity

Answer 2

Answer:

i)Both Assertion and Reason are true, and Reason is the correct explanation of the Assertion.

Explanation:

Velocity is a vector quantity, which means it is dependent on 2 factors: Magnitude and direction. If either of these quantities change, then velocity changes. Magnitude aka speed remains the same as stated in Assertion A, but direction changes, resulting in a change in velocity. Therefore (i) is the correct answer.
