please help me sovle this questionplease help me sovle this question let c be 2 vectors perpendicular to each other in XY plane all vectors in same plane having projectims 1&2 along resgy are given by Share with your friends Share 0 Neha Sethi answered this Dear student b→=4i+3jSo, c→=3λi-4λj for all values λ.We are choosing c→ such that b→.c→=0 as b→ and c → are ⊥.Let the required vector be a→=pi+qjProjection of a→ in the direction of b→=a→.b→b→1=4p+3q5So, 4p+3q=5 ...12=3λp-4λq±5λSo, 3p-4q=10 ...2or 3p-4q=-10 ...3Modulus of c→ is 5λ if λ>0 and -5λ if λ<0Solving 1 and 2, we get p=2,q=-1 and solving 1 and 3, we getp=-25 and q=115So, a→=2i-j or 15-2i+11j Regards 1 View Full Answer
