If `veca=2hati-hatj+2hatk and vecb=-hati+hatj-hatk` calculate `veca+vecb`

If veca=2hati-hatj+hatk and vecb=3hati+4hatj-hatk , prove that vecaxxvecb represents a vector which perpendicular to both veca and vecb .

If veca=2hati-3hatj-hatk and vecb=hati+4hatj-2hatk , then vecaxxvecb is

If veca = 2hati -3hatj-1hatk and vecb =hati + 4hatj -2hatk " then " veca xx vecb is

If veca=2hati + hatj + hatk , vecb=hati + 2hatj + 2hatk then [veca vecb veci] hati + [veca vecb vecj] hatj + [veca vecb hatk] k is equal to

If veca=3hati+hatj-4hatk and vecb=6hati+5hatj-2hatk find |veca Xvecb|

If veca=2hati+3hatj+hatk, vecb=hati-2hatj+hatk and vecc=-3hati+hatj+2hatk , then [veca vecb vecc]=

If veca=2hati+3hatj+hatk, vecb=hati-2hatj+hatk and vecc=-3hati+hatj+2hatk , then [veca vecb vecc]=

If veca=hati+2hatj-3hatk and vecb=3hati+hatj+2hatk show that the vectors veca+vecb and veca-vecb are perpendicular to other.

If veca = hati+hatj-2hatk, vecb=2hati-3hatj+hatk the value of (2veca+3vecb) . (2vecbxx3veca) is :

If veca=5hati-hatj-3hatk and vecb=hati+3hatj-5hatk , then show that the vectors veca+vecb and veca-vecb are perpendicular.
