Assertion: Vector addition of two vectors `vedA` and `vecB` is commutative.
Reason: `vecA+vecB=vecB+vecA`

Assertion: Vector addition is commutative. Reason: (vecA+vecB)!=(vecB+vecA)

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

For vectors vecA and vecB , (vecA + vecB). (vecA xx vecB) will be :

Assertion: vecA.vecB=vecB.vecA Reason: Dot product of two vectors is commutative.

What is the property of two vectores vec A and vec B if: (A) |vecA + vecB|= |vecA - vecB| (b) vecA + vecB = vecA - vecB

For any two vectors veca and vecb prove that |veca.vecb|<=|veca||vecb|

Show that, in case of vector addition vecA+vecB=vecB+vecA

(a) Show that vector adition is commutative but vector subtraction is non-commutative . (b) For vectors vecA=3hati-4hatj+5hatk and vecB=hati-hatj-hatk , calculate the value of (vecA+vecB)xx(vecA-vecB)
