सदिश `veca=2hati+hatj+3hatk` के अनुदिश मात्रक सदिश ज्ञात कीजिए।

Find veca. (vecb xx vecc) if veca=2hati + hatj + 3hatk , vecb= -hati + 2hatj + hatk and vecc = 3hati + hatj + 2hatk .

Given veca = 2hati + hatj - 8 hatk and vecb = hati + 3hatj - 4hatk then |veca + vecb| = ……………………… .

If veca = 3hati - hatj - 4hatk , vecb = -2hati + 4hatj - 3hatk and vec c = hati + 2hatj - hatk then |3veca - 2vec b + 4vec c | is equal to

If veca = 2hati -3hatj-1hatk and vecb =hati + 4hatj -2hatk " then " veca xx vecb is
