If vecb ne 0 , then every vector veca can be written in a unique manner as the sum of a vector veca_(p) parallel to vecb and a vector veca_(q) perpendicular to vecb . If veca is parallel to vecb then veca_(q) =0 and veca_(q)=veca . The vector veca_(p) is called the projection of veca on vecb and is denoted by proj vecb(veca) . Since proj vecb(veca) is parallel to vecb , it is a scalar multiple of the vector in the direction of vecb i.e., proj vecb(veca)=lambdavecUvecb" " (vecUvecb=(vecb)/(|vecb|)) The scalar lambda is called the componennt of veca in the direction of vecb and is denoted by comp vecb(veca) . In fact proj vecb(veca)=(veca.vecUvecb)vecUvecb and comp vecb(veca)=veca.vecUvecb . If veca=-2hatj+hatj+hatk and vecb=4hati-3hatj+hatk and veca=vec_(p)+veca_(q) then veca_(q) is equal to

vecA and vecB are two vectors. (vecA + vecB) xx (vecA - vecB) can be expressed as :

Magnitude of the cross product of the two vectors (vecA and vecB) is equal to the dot product of the two . Magnitude of their resultant can be written as

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 = |vecA xx vecB| , find angle between vecA and vecB .

vecA, vecB and vecC are vectors such that vecC= vecA + vecB and vecC bot vecA and also C= A . Angle between vecA and vecB is :

If vecAxxvecB=0, can you say that a. vecA=vecB, b. vecA!=vecB?

If |veca+ vecb| lt | veca- vecb| , then the angle between veca and vecb can lie in the interval
