Statement 1: Unit vector has a unit though its magnitude is one and Statement 2: Unit vector is obtained by dividing a vector by its own magnituded.

If P(-1,2) and Q(3,-7) are two points, express the vectors vec(PQ) in terms of unit vectors hatiand hatj . Also find the distance between points P and Q. What is the unit vector in the direction of vec(PQ) ? Verify that magnitude of unit vector indeed unity.

If magnitude of sum of two unit vectors is sqrt2 then find the magnitude of subtraction of these unit vectors.
