`veca =1/sqrt(10)(3hati + hatk)` and `vecb =1/7(2hati +3hatj-6hatk)`, then the value of `(2veca-vecb).[(vecaxxvecb)xx(veca+2vecb)]` is:

If veca=(hati-2hatj)/(sqrt(5)) and vecb=(2hati+hatj+3hatk)/(sqrt(14)), then the value of (2veca+vecb)".[(veca xx vecb)xx(veca-2vecb)]

If veca and vecb are vectors in space given by veca= (hati-2hatj)/sqrt5and vecb= (2hati + hatj + 3hatk)/sqrt14 then find the value of (2veca + vecb) . [(vecaxxvecb) xx (veca- 2vecb)]

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

If veca=3hati+4hatj-5hatk and vecb=7hati-3hatj+6hatk find a unit vector along (veca+vecb)xx(veca-vecb) .

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

If vecA=3hati+hatj+2hatk and vecB=2hati-2hatj+4hatk , then value of |vecA X vecB| will be

If veca=hati+hatj + hatk and vecb = hati - 2 hatj+hatk then find the vector vecc such that veca.vecc =2 and veca xx vecc=vecb .

If vecA= 4hati+nhatj-2hatk and vecB=2hati+3hatj+hatk , then findt the value of n so that vecA bot vecB .

If vecA= 4hati+nhatj-2hatk and vecB=2hati+3hatj+hatk , then findt the value of n so that vecA bot vecB .

If vecA= 3hati+2hatj and vecB= 2hati+ 3hatj-hatk , then find a unit vector along (vecA-vecB) .
