Assertion: Vector addition is commutative.
Reason: Two vectors may be added graphically using head- to-tail method or parallelogram method.

Text Solution

Verified by Experts

The correct Answer is:
B
Vector addition is commutative
i.e., `vecA + vecB = vecB + vecA`, where `vecA and vecB` are two vectors Two vectors `vecA and vecB` may be added graphically using head-to-tail method or parallelogram method.
