Expert Answer:

Adding any number of unit vectors will not give a unit vector.

No. The zero/null vector has zero magnitude, hence it's not possible to add two vectors of unequal magnitude and get a null vector.

Yes, it's possible to add 3 vectors of equal magnitude and get zero.

For example,

Following three vectors have the same magnitude of 2 and there addition gives a zero.

V1 = -2i, V2 = i + 3j, V3 = i - 3j
