Question

1. what is the resultant force? a) 0 n balanced b) 400 n right c) 40 n right d) 40 n left

Explanation:

Step1: Analyze forces in horizontal direction

There are no horizontal - direction forces given.

Step2: Analyze forces in vertical direction

The two forces acting on the cube are both 20 N and act in the same (down - ward) direction. The resultant force \(F_{net}\) in the vertical direction is the sum of these two forces. Using the formula \(F_{net}=F_1 + F_2\), where \(F_1 = 20N\) and \(F_2=20N\). So \(F_{net}=20N + 20N=40N\) (down - ward). Since there are no other forces to balance this vertical force, the resultant force on the cube is 40 N in the downward direction. If we consider the options in terms of direction and magnitude for a single - direction force situation, we assume the question is asking about the magnitude of the resultant force.

Answer:

C. 40 N right (assuming the downward direction is considered as 'right' in the context of the options, which is a bit of a mis - labeling in terms of standard direction but based on the options provided, the magnitude of the resultant force is 40 N)
