Properties of Scalar in Vector…
Properties of Scalar in Vector:(a) i.i = j.j = k.k = 1, because angle between two equal vectors is zero.
(b) If two vectors A and B are perpendicular vectors, then A.B = ABcos90° = 0 and i.j = j.k = k.i = 0
(c) for two vectors
A = axi + ayj + azk and B = bxi + byj + bzk
A.B = axbx + ayby + azbz
