A uniform have meter rule is freely pivoted at 15cm mark and it balances horizontal when a body of mass 40g is huge from the 2cm mark. Draw a clear force diagram of the rule
To draw a clear force diagram of the uniform meter rule, we need to consider the forces acting on it. Let's break it down step by step:
1. Start by drawing a vertical line to represent the meter rule, including the 15cm mark and the 2cm mark.
15cm 2cm
|----------------------|------------------------|-------------------------|
2. At the 15cm mark, draw a small arrow pointing upwards to represent the pivot point.
|----------------------|------------------------|-------------------------|
↑ 15cm 2cm
3. At the 2cm mark, draw a downward arrow to represent the force exerted by the suspended body of mass 40g.
|----------------------|------------------------|-------------------------|
↑ 15cm 2cm
↑
40g
4. Finally, label the arrow representing the upward force at the pivot as "Reaction force" and the arrow representing the downward force at the 2cm mark as "Weight of 40g body".
|----------------------|------------------------|-------------------------|
Reaction force 15cm 2cm
↑
40g
Weight of 40g body
This force diagram showcases the two main forces acting on the uniform meter rule: the upward reaction force at the pivot point and the downward weight force of the 40g body.
