If vecA xx vecB = vecC+ vecD, them select the correct alternative:

1.	If vecA xx vecB = vecC+ vecD, them select the correct alternative:
Answer» `vecB` is parallel to `vecC + VECD.` `vecA` is perpendicular to `vecC.` Component of `vecC` along `vecA` = component of `vecD` along `vecA` Component of `vecC` along `vecA =`- component of `vecD` along `vecA` Solution :According to DEFINITION of cross-product `vec(C)+vec(D)` is perpendicular to both `vec(A)andvec(B)` i.e., `vec(A).(vec(C)+vec(D))=0orvec(A). vec(C)+vec(A).vec(D)=0` or A (component of `vec(C)` along `vec(A)`) + A(component of `VCE(D)` along `vec(A)`)=0 or component of `vec(C)` along `vec(A)` =- component of `vec(D)` along `vec(A)`
