Question

scalar product of two vector​

Answer 1

Answer:

The result of a scalar product of two vectors is a scalar quantity. ... The condition for two vectors A = (Ax , Ay) and B = (Bx , By) to be perpendicular is that their scalar product is equal to zero: AxBx + AyBy = 0.

Answer 2

Scalar product we generally takes if we talk about general product in maths

Assume 2 vectors a and

their scale product a.b = |a||b| cosq

q is angle between a and b

|a|, |b| are their magnitudes

Don't represent direction

scalar product of same vector is simply

square of its magbitude as angle becomes 0 and between perpendicar vector its 0 as angle becomes 90 and cos90= 0
