Question

A particle starts from the origin goes along x axis at the point (10m,0)and returns along the same line to the point (-10m,0) the distance and displacement of particle during trip is
(1) 20 m, o
(2) 30 m, 10 m
(3) 30 m, - 10 m
(4) 20 m, - 10 m ​

Answer 1

Answer:

The distance and displacement of the particle during the trip are 30 m and -10 m.

Explanation:

Given that,

A particle start from the origin, goes along x-axis to the point (10m,0) and then returns along the same line to the point (-10m,0).

We need to draw the figure.

We calculate the distance

A particle moves 10 meter from the origin O to A along the x axis and then along the same line.

Now, a particle moves 10 m from A to O and 10 m O to B

The total distance is

The total distance is
d= 10+10+10=30m
The displacement is the shortest distance between starting point and end point.
D= -10m
Hence,  The distance and displacement of the particle during the trip are 30 m and -10 m.
