If `veca=2hati+hatj-3hatk, vecb=-hati+hatj+2hatk, vec c= 4hati+3hatk` then

If veca=2hati+hatj-hatk, vecb= -hati+2hatj+hatk, vecc=-hati+2hatj-hatk then the unit vector perpendicular to both veca+vecb and vecb +vec c is :

If veca=2hati+3hatj-hatk, vecb=3hati+5hatj+2hatk, vec c= -hati-2hatj+3hatk , verify that veca xx (vecb xx vec c)=(veca*vec c)vecb-(veca*vecb)vec c

If veca=2hati+3hatj-hatk, vecb=3hati+5hatj+2hatk, vec c= -hati-2hatj+3hatk , verify that (veca xx vecb) xx vec c=(veca *vec c) vecb-(vecb*vec c)veca

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 :

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 :

If veca=2hati+3hatj-hatk, vecb= -hati+2hatj-4hatk, vec c =hati+hatj+hatk , then find the value of (veca xx vecb)*(veca xx vec c) .

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca xx (vecb xx vec c)

If veca=hati-2hatj+3hatk, vecb=2hati+hatj-2hatk, vec c=3hati+2hatj+hatk , find veca*(vecb xx vec c) .
