If `veca=hati+2hatj-3hatk and vecb=3hati+hatj+2hatk` show that the vectors `veca+vecb` and veca-vecb` are perpendicular to other.

If veca=5hati-hatj+3hatk and vecb=hati+3hatj-5hatk then show that the vectors veca+vecb and veca-vecb are perpendicular.

If veca=5hati-hatj-3hatk and vecb=hati+3hatj-5hatk , then show that the vectors veca+vecb and veca-vecb are perpendicular.

If veca = 5hati-hatj-3hatk, vecb = hati+3hatj-5hatk then show that the vectors veca+vecb&veca-vecb are perpendicular

If a=4hati+2hatj-hatk and vecb=5hati+2hatj-3hatk find the angle between the vectors veca+vecb and veca-vecb

If veca=hati+2hatj-hatk and vecb=3hati+hatj-hatk find a unit vector int direction of veca-vecb .

If veca=3hati+hatj-4hatk and vecb=6hati+5hatj-2hatk find |veca Xvecb|

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

vecA=4hati+4hatj-4hatk and vecB=3hati+hatj+4hatk , then angle between vectors vecA and vecB is

If veca=2hati-hatj+hatk and vecb=3hati+4hatj-hatk , prove that vecaxxvecb represents a vector which perpendicular to both veca and vecb .
