Expert Answer:

Consider a point P in space.It can be specified by three coordinates x,y,z. Another way to specify this point is by joining this point P from origin O.Then the vector Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. specifies the position in space and is called the position vectior as it specifies a point(position) in space.
Let Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. can be resolved into three components along x,y and z axes.Let Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. and Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. be the unit vector along x, y and z axes.
then position vector can be written as Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
The magnitude of a vector can be determined by using Pythagorean theorem.The magnitude of position vector Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '. is
 Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
It represents the distance from the origin to that point on the coordinate system
