Question

A particle is moving in circular path of radius of 10m.The displacement after -- a) half cycle b) complete cycle.
Plezz answer this fast.... ​

Answer 1

Answer:

20m and 0 m

Explanation:

According to the given question,

r = radius = 10m

And we are asked displacement when the particle completes half and full cycle.

We know,

Displacement is the shortest length between two points.

When particle completes half cycle, means it's at the opposite side from where it started.

Thus displacement here will be equal to the diameter of the circle = 2r = 2×10=20m ans.

Again,

When the particle, completes full circle then it's final and initial position are same thus displacement = 0m ans.
