Let `veca=hati+2hatj and vecb=2hati+hatj. Is |veca|=|vecb"` Are the vectors `veca and vecb ` equal?.

Let veca=2hati-3hatj and vecb=3hati+2hatj. Is |veca|=|vecb|? Are the vectors vec a and vec b equal?

Let veca = 3hati + 2hatj and vecb = 2hati + 3hatj . Is |veca| = |vecb| ? Is veca = vecb ?

If veca=hati+hatj,vecb=hati-hatj , then veca.vecb=

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

Let veca =2hati +hatj -2hatk and vecb = hati +hatj . " Let " vecc be vector such that |vecc -veca|=3, |(veca xx vecb) xx vecc|=3 and the angle between vecc and veca xx vecb " be " 30^(@) Then , veca . Vecc is equal to

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

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