Question

The operation which does not give you a vector as an output from two vector inputs is ______

(b) Cross product

(c) Vector addition

(d) Vector subtraction

I got this question in semester exam.

I want to ask this question from Motion in a Plane in chapter Motion in a Plane of Physics – Class 11

Answer 1

The correct option is (a) Dot product

For explanation I would say: Vector addition and subtraction give a vector as the output. Cross product also gives a vector as the output. Only Dot product gives a scalar after acting on two vectors.
