Question

a particle is moving in circular path of radius r . what is displacement after traversing a complete cricle

Answer 1

Answer:

It is defined as the change in the position of the particle as it moves from one position to another. ... Initial position of the particle is B and the final position of the particle is A. Therefore, the shortest distance between A and B is 2r. Hence, displacement = 2r.

Answer 2

Explanation:

Displacement at half path is the shortest distance between the initial and final point.

So, it's equal to twice the radius of the circle =2r
