What is the projection of `vecA` on `vecB` ?

If vecA=2hati+3hatj-hatk and vecB=-hati+3hatj+4hatk then projection of vecA on vecB will be

If vecA=2hati+3hatj-hatk and vecB=-hati+3hatj+4hatk then projection of vecA on vecB will be

If vecA=2hati+3hatj-hatk and vecB=-hati+3hatj+4hatk then projection of vecA on vecB will be

If vecA=hati+hatj-hatk and vecB=-hati+3hatj+4hatk then projection of vecA on vecB will be

What is the projection vector of veca along vecb ?

If the projection of vecb on veca is twice the projection of veca on vecb , then |vecb|-|veca| is equal to :

Show that the projection of vecb on veca ne vec0 is : ((veca*vecb)/(|veca|^2))veca .

The projection vector of veca on vecb is

Let veca=hati+2hatj-3hatk and vecb=lamdahatj+3hatk . If the projection of veca on vecb is equal to the projection of vecb on veca , then the values of lamda are
