Write the projection of the vector on the vector

projection of a on b is given by:

|| = (1² + 1² + 0²)^1/2

⇒|| = (1 + 1)^1/2 = (2)^1/2

a unit vector in the direction of the sum of the vectors is given by:

Ans: the projection of the vector on the vector

Write the vector of magnitude 15 units in the direction of vector

If and find a vector of magnitude 6 units which is parallel to the vector

Write the angle between two vectors and with magnitudes and 2 respectively having

If and then find
