* MULTIPLICATION OF VECTORS 1. Dot Product (Scalar Product) The B scalar es or dot product of two vectors A an defined as product of magnitride of A and B and cosche of angle between them If A and B are vector I to each othu then theer scalar product is AB cos 90 0. If A and B arc two Il vectors having direction then their scalar product is AB COS O Same = AB If A and B au two Il vectors having opp. direction and their scalar product. AB= ABCOS 180 -AB A scalar product of vector with itselly equal to the square of its magnitude. A A COSO A 2 A SCALAR PRODUCT OF ORTHOGONAL UNIT VECTORS 2. Cross Product (vector Product) The vector ok is product of two vectors cross defined as the vector whose vector whose magnitude equal to the product of the magnitudes of the two vectors and sine the angle between them and whose direction is I to the plane of the two vectors and is given by night band screw (thumb cule) the vector product of two vectors ca expressed in terms of their rectangu components as determined.
