1.	Assertion: Two vectors are said to be equal if , and only if, they have the same magnitude and the same dirction. Reason: Addition and subtraction of scalars make sense only for quantities with same units.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 assertionC. If assertion is true but reason is false.D. If both aseertion and reason are false.
Answer» Correct Answer - B Addition and subtraction of scalars make sense only for quantities with same unit. But you can multiply and divide sacalrs of different units.
