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

If veca, vecb and vecc are non - zero vectors such that veca.vecb= veca.vecc ,then find the goemetrical relation between the vectors.

If veca, vecb and vecc are non - zero vectors such that veca.vecb= veca.vecc ,.the find the goemetrical relation between the vectors.

If veca, vecb are unit vectors such that |veca +vecb|=1 and |veca -vecb|=sqrt3 , " then " |3veca +2vecb|=

If veca, vecb are unit vectors such that |veca +vecb|=1 and |veca -vecb|=sqrt3 , then |3 veca+2vecb |=

If vecA and vecB are non-zero vectors which obey the relation |vecA+vecB|=|vecA-vecB|, then the angle between them is

If veca and vecb are two vectors such that |veca+vecb|=|veca| then prove that vector 2veca + vecb is perpendicular to vector vecb .

If veca and vecb are two vectors such that |veca+vecb|=|veca| , then prove that the vector 2veca+vecb is perpendicular to vector vecb .

If veca, vecb, vecc are three non-zero vectors such that veca + vecb + vecc=0 and m = veca.vecb + vecb.vecc + vecc.veca , then:

If veca, vecb, vecc are three non-zero vectors such that veca + vecb + vecc=0 and m = veca.vecb + vecb.vecc + vecc.veca , then:
