Question

Explain and define a unit vector. Also write unit vectors of Cartesian co-ordinate axes.​

Answer 1

Answer:

A vector is a quantity which has both magnitudes, as well as direction. A vector which has a magnitude of 1 is a unit vector. It is also known as Direction Vector. Any vector can become a unit vector by dividing it by the magnitude of the given vector. In coordinates, we can write i=(1,0). Similarly, the vector j is the unit vector in the direction of the positive y-axis: j=(0,1).

Answer 2

Answer:

A unit vector is a vector whose length is one. The vector i is the unit vector in the direction of the positive x-axis. In coordinates, we can write i=(1,0). Similarly, the vector j is the unit vector in the direction of the positive y-axis: j=(0,1).
