If two vectors
and
be such that 
, then the angle between them is
The magnitude of resultant of the two vectors of magnitude 4 and 3 is 1. The angle between them is
The value of the sum of two vectors
and
with θ as the angle between them is
Angle between two vectors 
and 
is θ, then angle between vector 
and 
is given by
A body is in the state of equilibrium under effect of three forces of equal magnitude. The angle between any two forces is
