Question

If a vector is equal to two icap-jcap+kcap b vector is equal to icap+jcap-2kcapand c vector is equal to icap+3 jcap-kcap such that a vector is perpendicular to lambda×b vector +c vector then find lambda

Answer 1

What is the projection of two vectors?

The vector projection is the vector produced when one vector is resolved into two component vectors, one that is parallel to the 2nd vector and one that is perpendicular to the 2nd vector. The parallel vector is the vector projection.
