Question

Q 28 A particle is moving in a circular path of radius r. The displacement after 2 circle would be:
(a) Zero
(b) πr
(c) 2r
(d) 2pie r

plz answer i will mark as brainlist​

Answer 1

Answer:

c) 2R

Explanation:

distance Travelled=22/7*R (pie*R)

Displacement is the shortest straight line distance covered by an object from its initial point to the final. So if an object is traveling around the circle of radius R then after covering a half circle its displacement will be equals to its diameter which will be 2R.

Answer 2

zero

no displacement took place here
