Question

a particle is moving along a circular path of radius r, when it makes half a rotation, the ratio bw its displacement and distance is?​

Answer 1

ANSWER:

2:π

Explanation:

displacement when it makes half a rotation is diameter that is 2 r.

distance covered will be half of the circumference of circle i.e. π r

ratio = displacement/ distance

2 r/ π r

2/π

so ratio is 2:π

Answer 2

Answer:

2Pi

is the answer which is ratio b/w displacement vand distance
