given that a(vector)=i(cap)-j(cap) and b(vector)=i(cap)+2j(cap) are two vectors find a unit vector coplanar with a(vector) and b(vector) and perpendicular to a(vector)
a=i-jb=i+2jc=xi+yja.c=x-y=0;x=yc=xi+xjthe unit vector is 1/sqrt(2)(i+j)thankssher mohammadb.tech, iit delhi
The capital letters denote the position vectors of the points:G = A + B + C/3G1 = P + Q + R/33(G-G1) = A-P + B - Q + C - R3GG1 = AP + BQ + CRThanksBharat Bajajaskiitians facultyIIT Delhi
