The object experiences two external forces: 60 N to the west and 130 N to the east. What is the net external force?

70 N to the East

Explanation:

lets assume east is positive and west is negative, since they are in opposite directions the net external force = F1+F2

Net force = (-60) + 130

Net force = 70

or

Net force = 70 N in the east direction

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

because growing process had stoped after 4-5 year
