.
The resulting force magnitude is


|F| =  =  grams.


Use your calculator.


To understand why it is so, use the parallelogram rule of adding forces (vectors) and make a sketch.

About adding vectors in a plane and about the parallelogram rule of adding vectors see the lesson

Notice. It was VERY long time ago when the force was measured in kilograms and grams.

In modern unit system the basic unit of force is Newton.
