Assertion : Velocity of a body is positive. So negative acceleration of the body is associated with a slowing down of the body. Reason : Acceleration is a vector quantity.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Given that velocity is positive. Negative acceleration of an object signifies a decrease in velocity. When a body slows down, it experiences negative acceleration, commonly referred to as retardation when the final velocity is smaller than the initial velocity. So correct option is (2).

Assertion : A scalar quantity is independent of the orientation of frame of reference. Reason : Vector may change if frame of reference is rotated.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
A scalar does not depend on frame of reference. If the frame of reference undergoes rotation or translation, the vector itself remains unchanged, although its components may experience alterations. So correct option is (3).

Assertion : If a physical quantity is a vector, it must have direction. Reason : Current has a direction therefore it is a vector quantity.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
In the case of physical quantities, having a direction implies that they may or may not be vectors, but the converse is not necessarily true.Some physical quantities, such as pressure, surface tension, and current, exhibit direction but are not considered vectors. So correct option is (3).

Assertion : A scalar has magnitude only. Reason : A scalar quantity is one that must be dimensionless.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Scalar quantities, such as speed, distance, and mass, solely possess magnitude, but they also have associated dimensions. So correct option is (3).
