Question

what is the value of B vector.B vector?​

Answer 1

Vector B Therefore A.(A×B) = |A| |A×B| cos(90) = 0.

is the value of vector B

Answer 2

THE DOT PRODUCT OF $vect B.vect B=|B|^{2} cos$θ.

Explanation:

• A vector quantity is a quantity which has both magnitude and direction.
• The symbol of vector is an arrow.
• Dot product is also called Scalar product of 2 vectors.
• If the two B vectors make an angle of θ with each other then the scalar product will be the square of the magnitude times the cosine of angle θ.
• If the magnitude of vectors is known, then the angle can be calculated.
• $vect B.vect B=|B|^{2} cos$θ

        cosθ=$\frac{B.B}{|B|^{2}}$
