Vectors are represented by an arrow
The arrowhead indicates the direction of the vector
The length of the arrow represents the magnitude
After the forces put on up which is 2n and on right side 5n force thus the force will be put on in the middle of up and right which would be force c
Calculating Vectors Graphically
Vectors at right angles to one another can be combined into one resultant vector
The resultant vector will have the same effect as the two original ones
To calculate vectors graphically means carefully producing a scale drawing with all lengths and angles correct
This should be done using a sharp pencil, ruler and protractor
Follow these steps to carry out calculations with vectors on graphs
Choose a scale which fits the page
For example, use 1 cm = 10 m or 1 cm = 1 N, so that the diagram is around 10 cm high
Draw the vectors at right angles to one another
Complete the rectangle
Draw the resultant vector diagonally from the origin
Carefully measure the length of the resultant vector
Use the scale factor to calculate the magnitude
Use the protractor to measure the angle
