The mass of the meter stick, given that the 0.30-kg object is hung from the zero end and the meter stick is balanced horizontally, is 0.58 Kg
How to calculate the mass of the meter stick?
First, we shall represent the question using a well defined diagram. Please see attached photo.
Now, from the attached photo, we have the following:
- Anti-clockwise moment = 0.30 × 33
- Clockwise moment = M × 17
- Mass of meter stick (M) =?
The mass of the meter stick can be calculated as follow:
Clockwise moment = Anti-clockwise moment
M × 17 = 0.30 × 33
M × 17 = 9.9
Divide both sides by 17
M = 9.9 / 17
M = 0.58 Kg
Therefore, we can conclude that the mass of the meter stick is 0.58 Kg
