Question

.Find a unit vector of 2 units in the direction of i+j ​

Answer 1

A unit vector is given by dividing the vector by its magnitude, so that the resulting vector has magnitude 1 and is in the same direction as the original vector.

For the vector î + j + k

$\frac{i + j + k}{ \sqrt{1 + 1 + 1} }$

$= \frac{i + j + k}{ \sqrt{3} }$
