If `veca`=`hati-hatj`, `vecb`= `3hatj-hatk` and `vecc`=`7hati-hatk`. Find a vector `vecd` which is perpendicular to both `veca` and `vecb` and `vecc.vecd`=1.

Let veca=hati+4hatj+2hatk,vecb=3hati-2hatj+7hatk and vecc=2hati-hatj+4hatk . Find a vector vecd , which is perpendicular to both veca and vecb and vecc*vecd=18 .

Let veca=hati+4hatj+2hatk,vecb=3hati-2hatj+7hatk and vecc=2hati-hatj+4hatk . Find a vector vecd , which is perpendicular to both veca and vecb and vecd*vecc=18 .

If veca=hati+4hatj+2hatk , vecb=3hati-2hatj+7hatk and vecc=2hati-hatj+4hatk then find a vector vecd (which is _|_ ar to both veca and vecb ) and vecc.vecd =15.

If veca=4hati+5hatj-hatk , vecb=hati-4hatj+5hatk and vecc=3hati+3hatj-hatk then find a vector vecd (which is _|_ ar to both veca and vecb ) and vecc.vecd =21.
