Question

Displacement of a body if it traveled 5 km positive x-axis and 3 km negative x-axis

  1. 2 km +x
  2. 2 km -x
  3. 3 km +x
  4. 5 km -x

hintHint:

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.
