​

Answer 1

Answer:

Scaler Product means Product of two vector with Cosine Angle Bw them So Its mean that abcostheta Then Take B vector First Or A vector Result Is same

The Magnitude of both the Vectors are same...

Hey you also Check It But if the answer is wrong then Report it.....

Answer 2

Answer:

COMMUTATIVE LAW FOR DOT PRODUCT - City Collegiate Consider two vectors and ,the angle between them is q. where represents the projection of vector onto the direction of vector . ... This shows that the dot product of two vectors does not chanfe with the change in the order of the vectors to be multiplied. This fact is known as the commutative of dot product.
