The diagram below shows a ruler balanced with the fulcrum at the 50-cm mark. Copy the diagram onto a sheet of paper and answer Questions 50-52 below.
Find an arrangement of a 50-g, a 100-g, a 200-g, and a 500-g mass that balances. Show all the calculations and indicate the positions the masses should occupy (as in Questions 50 and 51).
To explain: The procedure to place the given masses on the scale to balance on the fulcrum.
Answer to Problem 52A
Explanation of Solution
Given:
Formula used:
Using Torque equation,
Calculation:
Mass1 X Distance from left of the fulcrum = Mass2 X Distance from right of the fulcrum
Now, the distance of fulcrum with
Solving,
