Question
Displacement of a body if it traveled 5 km positive x-axis and 3 km negative x-axis
- 2 km +x
- 2 km -x
- 3 km +x
- 5 km -x
Hint:
5-3= 2km.
The correct answer is: 2 km +x
- The body is along X-axis in positive direction for 5 km.
- And than comes back along 3 km in negative x-axis.
- That means the total displacement of body would be 5-3= 2 km in positive x-axis from starting position.
