| Q. |
Starting position of an object is representedas x=5.1±0.2m and finishing position asy=6.9±0.3m. What will be the displacementand error in displacement? |
| A. | displacement = 1m, error = 0.5m |
| B. | displacement = 2m, error = 0.36m |
| C. | displacement = 1.8m, error = 0.36m |
| D. | displacement = 1.5m, error = 0.4m |
| Answer» C. displacement = 1.8m, error = 0.36m | |
| Explanation: displacement between two positions represented as x±Δx and y±Δy is iy- xi and error in displacement is (Δx2 | |
