Question

A particle moves along a circular path of radious R . the distance and displacement of a particle after complete revolution is - a. 0,2Πr b. 2Πr, 0 c. 0, Πr d. Πr , 0 ​

Answer 1

Answer:

b. 2Πr, 0

Explanation:

In one complete revolution, path covered is the circumference of the circle, that is, 2πr.

Therefore distance travelled is 2πr

Displacement is the perpendicular distance between the starting and the ending points. Here, since the starting and ending points are the same (as the particle came back to its original position after the revolution), the displacement is zero.

hope..it..helps..

Answer 2

Answer:

answer is zero because if it goes round in full circle 360° is same as 0°
