The vector veca = hati + hatj + (m + 1) hatk , vecb = hati + hatj + m hatk.vecc = hati - hatj + m hatk are coplanar for :

If veca = ahti - ahtk, vecb = x hati + hatj + (1-x) hatk and vecc = y hati + x hatj + 1(+ x -y) hatk, then [veca vecb vecc] depends on :

Let veca = hat i + hatj + hatk, vecb = hati + 2 hatk and vecc = x hati + (x -2) hatj + hatk. If the vector vecc lies in the plane of veca and vecb, then x equals :

Let veca = hati- hatk, vecb = x hati + hatj + (1-x) hatk and vec c = y hati + x hatj + (1+ x -y) hatk. Then [veca vecb vec c] depends on:

If the vectors vec c , veca = x hati + y hatj + z hatk and vecb = hatj are such that vec a , vec c and vecb form a right-handed system, then vec c is :
