Question

A student drew a net force diagram for a stone. What is the amount and direction of the net force acting on the stone?

A diagram shows forces acting on a stone. One arrow shows an upward force of 3 N. A second arrow shows an upward force of 1 N. A third arrow shows a downward force of 10 N.

0 N. The stone does not move.
0 N. The stone does not move.

4 N upward
4 N upward

6 N downward
6 N downward

10 N downward
10 N downward

Answer 1

To determine the net force acting on the stone, we need to sum the forces acting in both the upward and downward directions.

1. The upward forces are:
- 3 N upward
- 1 N upward
- Total upward force = 3 N + 1 N = 4 N upward

2. The downward force is:
- 10 N downward

Now we can calculate the net force:
- Net force = Total upward force - Downward force
- Net force = 4 N upward - 10 N downward
- Net force = -6 N

Since the result is negative, it indicates that the net force is downward.

Therefore, the correct answer is **6 N downward**.
