If `veca=8hati-6hatj`, then find the value of `|veca|`.

If veca = 4 hati - 3 hatj then find the value of | veca |

If veca=hati+hatj+hatk,hatb=hati-hatj+hatk,vecc=hati+2hatj-hatk , then find the value of |{:(veca.veca,veca.vecb,veca.vecc),(vecb.veca,vecb.vecb,vecb.vecc),(vecc.veca,vecc.vecb,vecc.vecc):}|

If veca=hati+hatj+hatk, vecb=hati-hatj+hatk, vec c=hati+2hatj-hatk , then the value of |(veca*veca,veca*vecb, veca*vecc),(vecb*veca, vecb *vecb,vecb*vecc),(vec c*veca, vec c*vec b,vec c*vec c)| is equal to :

Let veca=hati-hatj+hatk, vecb=2hati+hatj+hatk and vecc=hati+hatj-2hatk , then the value of [(veca, vecb, vecc)] is equal to

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 .

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

If vecA= hati+2hatj+3hatk, vecB=-hati+hatj + 4hatk and vecC= 3hati-3hatj-12hatk , then find the angle between the vector (vecA+vecB+vecC) and (vecAxx vecB) in degrees.

If veca.veci=veca.(hati+hatj)=veca.(hati+hatj+hatk) . Then find the unit vector veca .

Given veca=xhati+yhatj+2hatk,vecb=hati-hatj+hatk , vecc=hati+2hatj, veca botvecb,veca.vecc=4 then find the value of [(veca, vecb, vecc)] .
