If `hatixx(vecrxxhatj)+hatjxx(vecrxxhatj)+hatk(vecrxxhatk)=vecaxxvecb` then

For any vectors vecr the value of hatixx(vecrxxhati)+hatjxx(vecrxxhatj)+hatkxx(vecrxxhatk) , is

For any vectors vecr the value of hatixx(vecrxxhati)+hatjxx(vecrxxhatj)+hatkxx(vecrxxhatk) , is

For any vector veca prove that hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxhatk)=2veca

If hata=hati+2hatj+3hatk, hatb=hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxhatk) then length of vecb is equal to (A) sqrt(12) (B) 2sqrt(12) (C) 2sqrt(14) (D) 3sqrt(12)

If veca is any vector and hati,hatj and hatk are unit vectors along the x,y and z directions then hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck)= (A) veca (B) -veca (C) 2veca (D) 0

If veca is any vector and hati,hatj and hatk are unit vectors along the x,y and z directions then hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck)= (A) veca (B) -veca (C) 2veca (D) 0

If hata=hati+2hatj+3hatk, hatb=hatixx(vecaxxhati)+hatjxx(vecaxxhatj)+hatkxx(vedaxxhatk) then length of vecb is equal to (A) sqrt(12) (B) 2sqrt(12) (C) 2sqrt(14) (D) 3sqrt(12)

For an vector veca the value of hatixx(vecaxxveci)+hatjxx(vecaxxhatj)+hatkxx(vecaxxveck) , is

If hati xx[(veca-hatj)xxhati]+hatjxx[(veca-hatk)xxhatj]+veckxx[(veca-veci)xxhatk]=0 , then find vector veca .
