Vector Projection Formula Derivation: Properties & Dot Product
WebFind the position vector formula of a point R which divides the line joining P and Q in the ratio 2:1, (i) internally, and (ii) externally. Solution: Since point R divides PQ in the ratio 2:1. we have, m = 2 and n = 1 (i) R divides PQ internally From equation (2), we have \vec {r} = \frac {m\vec {b} + n\vec {a}} {m + n} WebThe vector projection is of two types: Scalar projection that tells about the magnitude of vector projection and the other is the Vector projection which says about itself and … NCERT Solutions For Class 12.
