Question

If angle between two vectors is acute angle
then dot product of that two vectors is
(A) Positive
(B) Negative
(C) Zero
(D) May be +ve or -ve​

Answer 1

Answer:

Positive

Explanation:

Hope it helps u :)

Answer 2

Answer:

positve

Explanation:

The angle between two vectors a and b is found using the formula θ = cos-1 [ (a · b) / (|a| |b|) ]. If the two vectors are equal, then substitute b = a in this formula, then we get θ = cos-1 [ (a · a) / (|a| |a|) ] = cos-1 (|a|2/|a|2) = cos-11 = 0°.
