To determine the magnitude of the downward force when you know the net force is 800 N, we need to consider the direction of the forces acting on the object.
Assuming a typical scenario, where there are two forces acting against each other (let's say an upward force and a downward force), the net force can be calculated using the following formula:
\[ \text{Net Force} = \text{Upward Force} - \text{Downward Force} \]
Given that the net force is 800 N, we can rearrange the equation to solve for the downward force. If we denote the upward force as \( F_{up} \) and the downward force as \( F_{down} \), we then have:
\[ 800 N = F_{up} - F_{down} \]
From this, we can express \( F_{down} \) as:
\[ F_{down} = F_{up} - 800 N \]
Without additional information about the upward force, we can analyze possible given responses:
1. If the upward force is 600 N (which is less than the net force), we get:
\[ F_{down} = 600 N - 800 N = -200 N \] (not possible)
2. If the upward force is 800 N, we find:
\[ F_{down} = 800 N - 800 N = 0 N \] (but does not match the options)
3. If the upward force is 1000 N, we get:
\[ F_{down} = 1000 N - 800 N = 200 N \] (this matches one of the options)
Thus, based on the possible scenarios and the provided answers, the correct magnitude of the downward force is **200 N**.
