The number of vectors of unit length perpendicular to the vectors hata = hati +hatj and vecb = hatj + hatk is

The number of vectors of unit length perpendicular to the vectors veca=2hati+hatj+2hatkandvecb=hatj+hatk is

In the question number 20, a unit vector perpendicular to the direction of vecA and vecB is

If veca, vecb, vecc non-zero vectors such that veca is perpendicular to vecb and vecc and |veca|=1, |vecb|=2, |vecc|=1, vecb.vecc=1 . There is a non-zero vector coplanar with veca+vecb and 2vecb-vecc and vecd.veca=1 , then the minimum value of |vecd| is

Let veca be a unit vector perpendicular to unit vectors vecb and vecc and if the angle between vecb and vecc " is " alpha , " then " vecb xx vecc is

If the vector vecb = 3hati + 4hatk is written as the sum of a vector vecb_(1) parallel to veca = hati + hatj and a vector vecb_(2) , perpendicular to veca then vecb_(1) xx vecb_(2) is equal to:

If veca,vecb,vecc are unit vectors such that veca is perpendicular to vecb and vecc and |veca+vecb+vecc|=1 then the angle between vecb and vecc is (A) pi/2 (B) pi (C) 0 (D) (2pi)/3

If veca , vecb , vecc are three mutually perpendicular unit vectors, then prove that ∣ ​ veca + vecb + vecc | ​ = sqrt3 ​
