The points with position vectors 5hati + 5hatk, -4hati + 3hatj - hatk and 2hati +hatj + 3hatk

The points with position vectors alpha hati+hatj+hatk, hati-hatj-hatk, hati+2hatj-hatk, hati+hatj+betahatk are coplanar if

If the vectors veca=2hati-hatj+hatk, vecb=hati+2hatj-hat(3k) and vecc= 3hati+lamda hatj+5hatk are coplanar the value of lamda is (A) -1 (B) 3 (C) -4 (D) -1/4

The vectors 3hati - hatj +2hatk, 2hati+hatj+3hatk and hati+lambdahatj-hatk are coplanar if value of lambda is (A) -2 (B) 0 (C) 2 (D) any real number

If the vectors 2hati-3hatj+4hatk and hati+2hatj-hatk and m hati - hatj+2hatk are coplanar, then the value of m is

Show that the vectors hati-hatj-hatk,2hati+3hatj+hatk and 7hati+3hatj-4hatk are coplanar.

If A, B, C and D are four points with position vectors 3hati, 3hatj, 3hatk and hati+hatj+hatk respectively, then D is the

If the vectors 2hati-hatj+hatk,hati+2hatj-3hatk and 3hati+ahatj+5hatk are coplanar, the prove that a=-4.
