Question

With respect to a rectangular cartesian
coordinate system, three vectors are expressed
as a=3ˆi-2ˆj,b= -2ˆi,c=ˆj-kˆ
r r r where ˆi,ˆj,kˆ are
unit vectors of axis x,y and z then the unit
vector ˆr along the direction of sum of these
vector is :-

Answer 1

Answer:

Explanation:

r(vector) = (3i –2j)+(–2i)+(j–k)

=>r =i–j–k

Unit vector along the direction of sum of these vectors is r^ =r(vector)/|r| =(i–j–k)/√
