When two vector `veca` and `vecb` are added, the magnitude of the resultant vector is always

When two vector vec a and vec b are added,the magnitude of the resultant vector is always

When two vectors vecA and vecB of magnitude a and b are added, the magnitude of the resultant vector is always

When two vectors A and B of magnitude a and b are added, the magnitude of the resultant vector is always :*

When two vectors vecA and vecB of magnitudes a and b respectively are added, the magnitude of resultant vector is always

When two vectors a and b of magnitudes 'a' and 'b' respectively are added, the magnitude of resultant vector is always

There are two vectors of equal magnitudes. When these vectors are added, then magnitude of the resultant is also equal to the magnitude of each of the two given vectors. Angle between the vectors is
