`|(vecaxxvecb)|^(2)` is eqaul to

If |vecaxxvecb|=2,|veca.vecb|=2 , then |veca|^(2)|vecb|^(2) is equal to

If |vecaxxvecb|=2,|veca.vecb|=2 , then |veca|^(2)|vecb|^(2) is equal to

Let veca=2hati+hatj-2hatk and vecb=hati+hatj . If vecc is a vector such that veca.vecc=|vecc|,|vecc-veca|=2sqrt(2) and the angle between vecaxxvecb and vecc is 30^(@) . Then |(vecaxxvecb)xxvecc) is equal to

The vector (veca-vecb)xx(veca+vecb) is equal to (A) 1/2 (vecaxxvecb) (B) vecaxxvecb (C) 2(veca+vecb) (D) 2(vecaxxvecb)

The vector (veca-vecb)xx(veca+vecb) is equal to (A) 1/2 (vecaxxvecb) (B) vecaxxvecb (C) 2(veca+vecb) (D) 2(vecaxxvecb)

vecaxxvecb is not equal to vecbxxveca . Why ?

[((vecaxxvecb)xx(vecbxxvecc),(vecbxxvecc)xx(veccxxveca),(veccxxveca)xx(vecaxxvecb))] equal to

If |vecaxxvecb|^(2)+|veca.vecb|^(2)=144 and |veca|=3 then |vecb| is equal to

(vecAxxvecB)+(vecBxxvecA) is equal to

(vecaxxvecb).(veccxxvecd) is not equal to
