`vecA = 2hati + 3hatj + 5hatk`
`vecB = hati + 2hatj + 3hatk`  then find `vecA . vecB`

If veca = (3hati + hatj - 5hatk) and vecb = (hati + 2hatj - hatk) then find a unit vector in the direction of (veca-vecb) .

Given : vecA = 2hati - hatj + 2hatk and vecB = -hati - hatj + hatk . The unit vector of vecA - vecB is

If veca = (-hati + hatj - hatk) and vecb = (2hati- 2hatj + 2hatk) then find the unit vector in the direction of (veca + vecb) .

If veca = (hati - 2hatj -3hatk) and vecb = (2hati + 4hatj +9 hatk) then find a unit vector parallel to (veca + vecb) .

If vecA = hati + 2hatj - hatk , vecB = - hati + hatj - 2hatk , then angle between vecA and vecB is

If veca = 5 hati- 4 hatj + hatk, vecb =- 4 hati + 3 hatj - 2 hatkand vec c = hati - 2 hatj - 2 hatk, then evaluate vec c. (veca xx vecb)

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

If veca = 2 hati - 3hatj, vecb = hati + hatj -hatk, vecc = 3hati - hatk, find [a vecb vecc]

If veca=hati+hatj + hatk and vecb = hati - 2 hatj+hatk then find the vector vecc such that veca.vecc =2 and veca xx vecc=vecb .

If veca=hati+hatj + hatk and vecb = hati - 2 hatj+hatk then find the vector vecc such that veca.vecc =2 and veca xx vecc=vecb .
