Question

A particle starts from the origin, goes along x-axis to the point (20m,0) and then returns along the same line to the point (20m,0). The distance and the displacement of the particle during the trip are
a. 40m,0
b. 40m, 20m
c. 40m, -20m
d. 60m, -20m

Answer 1

There is a mitake in our question in returninng, it is (-20m,0)

Sol..i) Distance travelled = 20 + 20 + 20 = 60 m
(ii) Displacement is only OB = 20 m in the negative direction. Displacement → Distance between final and initial position.

So answer is option d
