Accepted Answer

To find out which box contains the defective balls using the electronic weighing machine and only one chance, you can follow this strategy:

1. Label the boxes from 1 to 10.
2. Take one ball from box 1, two balls from box 2, three balls from box 3, and so on, until you take ten balls from box 10. This totals to 55 balls (1 + 2 + 3 + ... + 10 = 55).
3. Now, place all these balls on the weighing machine.
4. If all the balls were of equal weight (non-defective), then the total weight would be 55 * 10g = 550g.
5. However, if one of the boxes contains defective balls, it would be lighter, because each defective ball weighs 1g less.
6. The difference in weight would indicate which box contains the defective balls. For example, if the total weight is less than 550g, divide the difference by 1 to find out which box is defective.

For example, if the total weight is 545g, then the box with the defective balls is box 5 because the total weight is short by 5 grams (550g - 545g = 5g), indicating that box 5 has the defective balls.
