Unit Vectors

The resultant of two vectors of magnitudes 3 units and 4 units 5 units. What is the angle between the vectors ?

If veca and vecb are two unit vectors such that veca+vecb is also a unit vector, then find the angle between vectors veca and vecb .

The resultant of two vectors of magnitude 3 unit and 4 unit is 5 unit. The angle between these two vectors will be---

If the sum of two unit vectors is also a vector of unit magnitude, the magnitude of the difference of the two unit vectors is
