If `veca=(hati+hatj+hatk),veca*vecb=1 and vecaxxvecb=hatj-hatk.` Then `vecb` is

If veca = (hati + ahtj + hatk), veca.vecb=1 and veca xx vecb=hatj-hatk then vecb is :

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

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

If veca=(hati+hatj+hatk), and veca.vecb=1 and vecaxxvecb = -(hati-hatk) then vecb is (A) hati-hatj+hatk (B) 2hatj-hatk (C) hatj (D) 2hati

If veca=2hati-3hatj+4hatk, veca.vecb=2 and veca xx vecb=hati+2hatj+hatk , then vecb is equal to

If veca=2hati-3hatj+4hatk, veca.vecb=2 and veca xx vecb=hati+2hatj+hatk , then vecb is equal to

If veca=3hati-hatj+2hatk and vecb=2hati+3hatj+3hatk then veca.vecb is equal to :

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

If veca=hati-hatj+3hatk and vecb=2hati+3hatj-5hatk then find vecaxxvecb . Verify that veca and vecaxxvecb are perpendicular to each other.
