If `vecA =( hati + 2 hatj +5hatk)` and `vecB =( hati + 5 hatj +7hatk)` , then what would be the projection of `vec A` on `vec B` ?

If vecA= (2hati + 3hatj + 5hatk) and vecB = (hati+ 6hatj+6hatk) , then projection of vecA on vecB would be

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

If vecF = 3hati + 4hatj+5hatk and vecS=6hati +2hatj+5hatk , the find the work done.

find vecA xx vecB if vecA = hati - 2 hatj + 4 hatk and vecB = 3 hati - hatj + 2hatk

Let veca= 2 hati + 3hatj - 6hatk, vecb = 2hati - 3hatj + 6hatk and vecc = -2 hati + 3hatj + 6hatk . Let veca_(1) be the projection of veca on vecb and veca_(2) be the projection of veca_(1) on vecc . Then veca_(1).vecb is equal to

Let veca= 2 hati + 3hatj - 6hatk, vecb = 2hati - 3hatj + 6hatk and vecc = -2 hati + 3hatj + 6hatk . Let veca_(1) be the projection of veca on vecb and veca_(2) be the projection of veca_(1) on vecc . Then veca_(2) is equal to

If vecA= 6hati- 6hatj+5hatk and vecB= hati+ 2hatj-hatk , then find a unit vector parallel to the resultant of veca & vecB .

If two vectors are given as veca = hati - hatj + 2hatk and vecb = hati + 2hatj+hatk , the unit vector perpendicular to both vec a and vec b is

If veca =hati + hatj-hatk, vecb = - hati + 2hatj + 2hatk and vecc = - hati +2hatj -hatk , then a unit vector normal to the vectors veca + vecb and vecb -vecc , is

If vecF=3hati-4hatj+5hatk " and " vecS=6hati+2hatj+5hatk , the find the work done.
