Question

A particle starts from the origin goes along the x-axis to the point 20 m and 0 and returns along the same line to the point - 20 m and 0 the distance and displacement of the particle during the trip are

Answer 1

Distance =20{till point20,0)}+20(till origin)+20{till point (-20,0)}=60m
Displacement=(-20)m{from origin to point(-20,0)}

Answer 2

displacement will be 20
