4) Calculate the net force *

3 N

10-7= 3

the arrows are opposing each other.

The net or resultant force depende on the direction we can easily understood the directions are opposite .Force is vector so if vectors are opposite we difference the two vectors.

10N-7N=3N

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

we need the questions , i may then you.
