Find `|veca-vecb|`, if two vectors `veca and vecb` are such that `|veca|=2,|vecb|=3 and veca.vecb=4`.

Find |veca-vecb| , if two vector veca and vecb are such that |veca|=4,|vecb|=5 and veca.vecb=3

Two vectors vecA and vecB are such that vecA+vecB=vecA-vecB . Then

For any two vectors veca and vecb prove that |veca.vecb|lt+|veca||vecb|

If veca, vecb, vecc are vectors such that veca.vecb=0 and veca + vecb = vecc then:

Let veca and vecb are vectors such that |veca|=2, |vecb|=3 and veca. vecb=4 . If vecc=(3veca xx vecb)-4vecb , then |vecc| is equal to

If veca and vecb are non - zero vectors such that |veca + vecb| = |veca - 2vecb| then

veca and vecb are two vectors such that |veca|=1 ,|vecb|=4 and veca. Vecb =2 . If vecc = (2vecaxx vecb) - 3vecb then find angle between vecb and vecc .

Let veca,vecb and vecc are vectors such that |veca|=3,|vecb|=4and |vecc|=5, and (veca+vecb) is perpendicular to vecc,(vecb+vecc) is perpendiculatr to veca and (vecc+veca) is perpendicular to vecb . Then find the value of |veca+vecb+vecc| .

If veca " and " vecv are the two vectors such that |veca| = 3sqrt3,|vecb| = 4 " and " |veca + vecb|= sqrt7 , then the anlge between veca and vecb is
