Question

Find the unit vector that has the same direction as the vector v.v=10i

Answer 1

In this case the vector that has the same directiion as v=10i is:

Lets first find the magnitude of the given vector:

`|v|=\sqrt[]{10^2}=10`

Now we have the formula: v/|v|=u

`u=(10i)/(10)=i`

So the unit vector that has the same direction as the given one is u=i,
