Solution
To calculate the resultant force from a vector diagram, you would:
-
Draw the vectors on a graph. Each vector is represented by an arrow. The direction of the arrow shows the direction of the force, and the length of the arrow represents the magnitude of the force.
-
Arrange the vectors to be added in a 'tip-to-tail' method. This means the tail (start) of the second vector is at the tip (end) of the first vector, and so on.
-
Draw the resultant vector. This vector starts from the tail of the first vector and ends at the tip of the last vector.
-
Measure the length and direction of the resultant vector. The length gives you the magnitude of the resultant force and the direction gives you the direction of the resultant force.
So, the correct answer is (Choice D) Draw the vectors tip-to-tail.
