A uniform metre rule rests horizontally on a knife edge at the 60cm mark when a mass of 10g is suspended from one end. Draw a diagram of the arrangement. (a) At which end must this mass be suspended (b) What is the mass of the rule? (c ) THe 10g mass is now shifted to the 90cm mark. In which direction must the knife edge be shifted to make the rule horizontal again?

To solve the problem step by step, let's break it down into parts as per the question.
### Step 1: Draw the Diagram
1. **Draw a horizontal line** to represent the meter rule.
2. **Mark the ends of the meter rule**: Label the left end as A (0 cm) and the right end as B (100 cm).
3. **Mark the knife edge** at the 60 cm position.
4. **Indicate the center of mass** of the uniform meter rule at the 50 cm mark.
5. **Show the 10 g mass** suspended from one end (B).
