Assertion - (AxxB) .(BxxA) "is" - a^(2) B^(2) Sin^(2)theta Here there is the between A and B. Reason (AxxB) and (BxxA) are two anti - paralle3l vectors provided A and B are neither parallel nor anti - parallel .

Assertion - (AxxB) .(BxxA) "is" - a^(2) B^(2) Sin^(2)theta Here there

1.	Assertion - (AxxB) .(BxxA) "is" - a^(2) B^(2) Sin^(2)theta Here there is the between A and B. Reason (AxxB) and (BxxA) are two anti - paralle3l vectors provided A and B are neither parallel nor anti - parallel .
Answer» If both Assetion and Reason are correct but Reason is the correct explanation of Assertion. If both Assetion and Reason are correct but Reason is not the correct explanation of Assertion. If Asserion is true but Reason is false If Asserion is false but Reason is true Solution :(B) Angle between `AxxB`and BxxA is` 180^(@)` THEREFORE `(AxxB).(BxxA)=(ABsin THETA)(ABsintheta)(cos180^(@))` ` =-A^(2)B^(2) SIN ^(2) theta`
