If vector A is perpendicular to vectors B and `|vecA + vecB| =n|vecA +vecB|` then the value of n.

Let veca and vecb be two non-zero vectors perpendicular to each other and |veca|=|vecb| . If |veca xx vecb|=|veca| , then the angle between the vectors (veca +vecb+(veca xx vecb)) and veca is equal to :

If veca,vecb are vectors perpendicular to each other and |veca|=2, |vecb|=3, vecc xx veca=vecb , then the least value of 2|vecc-veca| is

If veca,vecb are vectors perpendicular to each other and |veca|=2, |vecb|=3, vecc xx veca=vecb , then the least value of 2|vecc-veca| is

If veca,vecb are vectors perpendicular to each other and |veca|=2, |vecb|=3, vecc xx veca=vecb , then the least value of 2|vecc-veca| is

If veca,vecb are vectors perpendicular to each other and |veca|=2, |vecb|=3, vecc xx veca=vecb , then the least value of 2|vecc-veca| is

If veca an vecb are perpendicular vectors, |veca+vecb|=13 and |veca|=5 , find the value of |vecb| .

if veca, vecb and vecc are there mutually perpendicular unit vectors and veca ia a unit vector then find the value of |2veca+ vecb + vecc |^2

if veca, vecb and vecc are there mutually perpendicular unit vectors and veca ia a unit vector then find the value of |2veca+ vecb + vecc |^2

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| .
